Populate a memory_info struct with PEI and SPD data, in order to inject
the CBMEM_INFO table necessary to populate a type17 SMBIOS table.
On Broadwell, this is done by the MRC binary, but the older Sandy Bridge
MRC binary doesn't populate the pei_data struct with all the info
needed, so we have to pull it from the SPD.
Some values are hardcoded based on platform specifications.

Using `config_of(dev)` to access `dev->chip_info` will make coreboot die
if the latter is NULL, which is the case for devices detected at runtime
(i.e. not statically declared in the devicetree). Given that the code is
designed to work when the PEG config is all-zeroes (devicetree default),
dying because `dev->chip_info` is NULL is foolish and unwarranted.
Introduce a helper function that returns a pointer to devicetree config
when available, and otherwise returns a pointer to a zero-filled static
struct. In addition, avoid an out-of-bounds access in the very unlikely
case where the device's function is too large.
Tested on Asrock B85M Pro4, can now boot when `device pci 01.0 on end`
is commented out in its devicetree. Without this commit, it could not.

GDXCBAR and EDRAMBAR are accounted for when reporting resources to the
allocator, but they are not present in the DSDT. In addition, coreboot
does not enable either range, but MRC.bin sets up GDXCBAR and does not
disable it afterwards. Not reporting GDXCBAR in the DSDT can result in
resource conflicts, and not enabling EDRAMBAR can cause issues on CPUs
with eDRAM.
Enable both GDXCBAR and EDRAMBAR in coreboot code, and report these
ranges in the DSDT. This matches what Broadwell does. The value for
the `GDXC_BASE_ADDRESS` macro matches what MRC.bin programs as well.
Tested on Asrock B85M Pro4 with an i7-4770S (no eDRAM):
- Still boots
- EDRAMBAR is now enabled with base address of 0xfed80000
- GDXCBAR is still mapped with base address of 0xfed84000

The {MCH,DMI,EP}BAR macros can be used for both reading and writing.
While this can sometimes be useful, compile-time overflow checking is
limited. Moreover, and-masks need to be bit-wise negated, which is easy
to forget and may result in spurious overflow warnings, and silencing
them with a cast also suppresses true integer overflow issues.
To address these limitations and for consistency with the existing MMIO
API (arch/mmio.h and device/mmio.h), these macros will be replaced with
prefixed wrappers around MMIO API functions. However, existing platform
code needs to be refactored, and the risk of introducing regressions is
substantial. To minimize the risk of breakage, the bulk of the platform
code changes will be verified using reproducible builds.
This patch introduces the new accessors, to be put to use in follow-ups.
These accessors are implemented as macros so that subsequent commits can
be verified using reproducible builds. They will be replaced with actual
functions after refactoring all platforms.

Haswell MRC.bin can return zero even when raminit did not complete
successfully. When this happens, the memory controller will not have
acknowledged raminit: the mc_init_done_ack bit in the MC_INIT_STATE_G
register will be zero, and memory accesses will lock up the system.
To handle this situation more gracefully, check the mc_init_done_ack bit
after running MRC. If the bit is not set, log a fatal error and halt.
Tested on Asrock B85M Pro4:
- With badly-seated DIMMs, MRC raminit fails and coreboot dies.
- After reseating the DIMMs, the board still boots successfully.

There's no good reason to use values smaller than 2 GiB here. Well, it
increases available DRAM in 32-bit space. However, as this is a 64-bit
platform, it's highly unlikely that 32-bit limitations would cause any
issues anymore. It's more likely to have the allocator give up because
memory-mapped resources in 32-bit space don't fit within the specified
MMIO size, which can easily occur when using a discrete graphics card.

Mainboards do not need to know about `pei_data` to tell northbridge code
where to find the SPD data. Adjust `mb_get_spd_map` to take a pointer to
a struct instead of an array, and update all the mainboards accordingly.
Currently, the only board with memory-down in the tree is google/slippy.
Mainboard code now obtains the SPD index in `mb_get_spd_map` and adjusts
the channel population accordingly. Then, northbridge code reads the SPD
file and uses the index that was read in `mb_get_spd_map`, and copies it
to channel 0 slot 0 unconditionally. MRC only uses the first position of
the `spd_data` array, and ignores the other positions. In coreboot code,
`setup_sdram_meminfo` uses the data of each SPD index, so `copy_spd` has
to account for this.

Using MCHBAR32_AND_OR() in these two cases changes the order of
additions slightly. Originally, the MCHBAR offset and the base
register offset (0x5a4/0x5b4) were added first. Due to the added
parentheses in the register macros, now the complete register
offset is calculated first and then added to MCHBAR. Associativity
tells us that this doesn't change the result.
Changes in the resulting binary were verified manually on the
object file.

Command timing is the absolute value of the most negative `pi_coding`
value across all ranks, or zero if there are no negative values. Use the
MAX() macro to ease proving that `cmd_delay` can never be negative, and
then drop the always-false underflow check.
The variable type for `cmd_delay` still needs to be signed because of
the comparisons with `pi_coding`, which is a signed value. Using an
unsigned type would result in undefined and also undesired behavior.

Clock is a differential signal and propagates faster than command and
control, therefore its timing needs to be offset with `pi_code_offset`.
It is also a periodic signal, so it can safely wrap around.
To avoid potential undefined behavior, make `clk_delay` signed. It makes
no difference with valid values, because the initial value can be proven
to never be negative and `pi_code_offset` is always positive. With this
change, it is possible to add an underflow check, for additional sanity.

To allow adjusting the phase shift of the various I/O signals, the
memory controller contains several PIs (Phase Interpolators). These
devices subdivide a QCLK (quarter of a clock cycle) in 64 `ticks`,
and the desired phase shift is specified in a register. For shifts
larger than one QCLK, there are `logic delay` registers, which allow
shifting a whole number of QCLKs in addition to the PI phase shift.
The number of PI ticks in a QCLK is often used in raminit calculations.
Define the `QCLK_PI` macro and use it in place of magic numbers. In
addition, add macros for other commonly-used values that use `QCLK_PI`
to avoid unnecessarily repeating `2 * QCLK_PI`, such as `CCC_MAX_PI`.
