Fill in the maximum DRAM capacity and slot count read from CAPID0_A
registers on Sandy Bridge and Haswell.
While the register isn't part of the Core Series datasheet, it can be
found in the corresponding "Intel Open Source Graphics Programmer's
Reference" datasheets.
Note that the values for DDRSZ (maximum allowed memory size per channel)
need to be halved when only one DIMM per channel is supported. On mobile
platforms, all but quad-core processors are subject to this restriction.
Tested on Lenovo X230:
On Linux, verify that `dmidecode -t 16` reports the actual maximum
capacity (16 GiB) instead of the currently-installed capacity (4 GiB) or
the max capacity assuming two DIMMs per channel is possible (32 GiB).

On Haswell platforms, the processor and the PCH are two separate dies,
and communicate through a high-speed bus. This is DMI (Direct Media
Interface) on traditional two-package platforms, but single-package
Haswell LP variants use OPI (On-Package Interconnect) instead.
Since OPI is not routed through the mainboard, most link parameters are
static and cannot be changed. OPI self-initializes on boot, anyway.
However, DMI needs to be initialized in firmware. On Haswell, the MRC
initializes the physical DMI link, but things like topology and power
management need to be configured as well. And we don't do that properly.
We enable ASPM on the PCH side of the DMI link, but not on the SA side.
Both sides need to use the same settings, so enable DMI ASPM on the SA.
Clearing the error status bits needs to be done on all Haswell variants.
Tested on Asrock B85M Pro4, still boots.

This function was copy-pasted, comments included, from Sandy Bridge.
However, it is only called with 0x0044 as the northbridge's PCI ID.
Therefore, `bridge_silicon_revision() & BASE_REV_MASK` will always
evaluate to 0x40, which never equals `BASE_REV_SNB`, that is, 0x00.
As the condition is always false, treat this code as dead and drop it.
Following a similar reasoning, all direct comparisons against SNB
steppings will always be true, because `bridge_silicon_revision()`
returns at least 0x40 which is always larger than either `SNB_STEP_D0`
or `SNB_STEP_D1`. So, drop all but the code path that is actually used.

The chipset code was incorrectly adding memory resources
to the domain device after resource allocation occurred.
It's not possible to get the correct view of the address space,
and it's generally incorrect to not add resources during
read_resources(). Fix the order by hanging the resources off
of the host bridge device.

We only write to the IOSAV LFSR registers twice, but we do so between
the writes to the other four IOSAV per-subsequence registers. Since we
know that the IOSAV is sleeping when we program the subsequences, we
might as well do the two oddball LFSR register writes after we have
programmed the always-written-to group of four registers. That way,
subsequent changes can reproducibly replace the four writes with a
single macro.

vboot_recovery_mode_enabled() was recently changed to assert() when it
is called before vboot logic has run, because we cannot determine
whether we're going to be in recovery mode at that point and we wanted
to flush out existing uses that pretended that we could. Turns out there
are a bunch of uses like that, and there is some code that is shared
across configurations that can and those that can't.
This patch cleans them up to either remove checks that cannot return
true, or add explicit Kconfig guards to clarify that the code is shared.
This means that using a separate recovery MRC cache is no longer
supported on boards that use VBOOT_STARTS_IN_ROMSTAGE (this has already
been broken with CB:38780, but with this patch those boards will boot
again using their normal MRC caches rather than just die). Skipping the
MRC cache and always regenerating from scratch in recovery mode is
likewise no longer supported for VBOOT_STARTS_IN_ROMSTAGE.
For FSP1.1 boards, none of them support VBOOT_STARTS_IN_BOOTBLOCK and
that is unlikely to change in the future so we will just hardcode that
fact in Kconfig (otherwise, fsp1.1 raminit would also have to be fixed
to work around this issue).

The WDB (Write Data Buffer) is a data region in CAR, used as a
scratchpad in the read and write training algorithms of memory
initialization. Both SNB and IVB use this buffer, but HSW does not.
Unlike earlier chipsets, Haswell contains much more in-hardware memory
training machinery, known as REUT (Robust Electrical Unified Testing).
Among other changes, the REUT hardware has a pattern storage buffer,
which renders the need for a pattern storage buffer in CAR obsolete.
Deprecate the WDB-related parameters in the pei_data structure for
Haswell, as they are leftovers from the previous generation's MRC.
Remove them from the mainboards, and explain why they are not required.
Because the MRC ABI has to remain the same, the layout of pei_data must
not be changed, so rename the WDB parameters instead of deleting them.
Tested on Asrock B85M Pro4, still boots with the MRC from Google Wolf.

Simplify generation of GMA SSDT, using updated naming convention.
If acpi_fill_ssdt is being invoked, then we know the IGD device is
present and enabled, so we can skip those checks. And the SSDT
generator now checks that the gfx struct is populated, so we can
skip that too.

These two identifiers were always very confusing. We're not filling and
injecting generators. We are filling SSDTs and injecting into the DSDT.
So drop the `_generator` suffix. Hopefully, this also makes ACPI look a
little less scary.

Including gma.asl at the platform level (vs the board level)
means that even desktop boards need to include the default
brightness levels, which makes no sense. To begin to clean this up,
include gma.asl in default_brightness_levels.asl (as well as
the handful of board-specific brightness files) and remove it
from the various platforms.
A follow-on commit will remove default_brightness_levels.asl
from all boards which lack an internal display.

Further backport the backlight-PWM handling from Skylake. Beside
configuring the PWM frequency in Hz, we also use the PCH's logic
for the brightness setting via BLM_PCH_OVERRIDE_ENABLE. Linux
would toggle it anyway and that might confuse our ASL code.
We assume that the 183Hz value that was set before for Slippy
variants was overridden by Linux with the 200Hz VBT value, like
it was for the Broadwell Chromebooks. So we set 200Hz for them
in the devicetrees. The calculated value for the T440p of 220Hz
seems sane and also matches the VBT.
