All the boards in the patch have a constraint for the I2C bus to operate
on 100 kHz. Provide dedicated values for rise time, fall time and data
hold time on mainboard level to get a proper timing which takes the bus
load into account. Giving these values the driver computes the needed
timings correctly.

Provide a SOC_INTEL_SKYLAKE_LGA1151_V2 option to select correct defaults

Intel provides AmberLakeFspBinPkg to support this combination,

1) Provide SOC_INTEL_SKYLAKE_LGA1151_V2 option that selects
PLATFORM_USES_FSP2_1, SOC_INTEL_COMMON_SKYLAKE_BASE and
SKYLAKE_SOC_PCH_H.
2) Add Amberlake FSP support.
If SOC_INTEL_SKYLAKE_LGA1151_V2 is set, use AbmerLakeFspBinPkg instead
of KabylakeFspBinPkg.
3) Enable Coffee Lake CPUs support.
If SOC_INTEL_SKYLAKE_LGA1151_V2 is set, select
MAINBOARD_SUPPORTS_COFFEELAKE_CPU.
4) Increase stack and heap size in CAR.

The existing helpers for reading/writing MSRs (rdmsr, wrmsr) require use
of the struct `msr_t`, which splits the MSR value into two 32 bit parts.
In many cases, where simple 32 bit or 64 bit values are written, this
bloats the code by unnecessarly having to use that struct.
Thus, introduce the helpers `msr_read` and `msr_write`, which take or
return `uint64_t` values, so the code condenses to a single line or two,
without having to deal with `msr_t`.
Example 1:
~~~
msr_t msr = {
.lo = read32((void *)(uintptr_t)0xfed30880),
.hi = 0,
};
msr.lo |= 1;
wrmsr(0x123, msr);
~~~
becomes
~~~
uint32_t foo = read32((void *)(uintptr_t)0xfed30880);
msr_write(0x123, foo | 1)
~~~
Example 2:
~~~
msr_t msr = rdmsr(0xff);
uint64_t msr_val = (msr.hi << 32) | msr.lo;
~~~
becomes
~~~
uint64_t msr_val = msr_read(0xff);
~~~

This adds full EINJ support with trigger action tables. The actual
error injection functionality is HW specific. Therefore, HW specific
code should call acpi_create_einj with an address where action table
resides. The default params of the action table are filled out by the
common code. Control is then returned back to the caller to modify or
override default parameters. If no changes are needed, caller can
simply add the acpi table. At runtime, FW is responsible for filling
out the action table with the proper entries. The action table memory
is shared between FW and OS. This memory should be marked as reserved
in E820 table.
Tested on Deltalake mainboard. Boot to OS, load the EINJ driver (
modprobe EINJ) and verify EINJ memory entries are in /proc/iomem.
Further tested by injecting errors via the APEI file nodes. More
information on error injection can be referenced in the latest ACPI
spec.

Some platforms which have large amounts of RAM and also write-combining
regions may decide to drop the WC regions in favor of the default when
preserving MTRRs for the OS. From a data safety perspective, this is
safe to do, but if, say, the graphics framebuffer is the region that is
changed from WC to UC/WB, then the performance of writing to the
framebuffer will decrease dramatically.
Modern OSes typically use Page Attribute Tables (PAT) to determine the
cacheability on a page level and usually do not touch the MTRRs. Thus,
it is believed to be safe to stop reserving MTRRs for the OS, in
general; PentiumII is the exception here in that OSes that still
support that may still require MTRRs to be available. In any case, if
the OS wants to reprogram all of the MTRRs, it is of course still free
to do so (after consulting the e820 table).

TEST=Verify MTRR programming on a brya (where `sa_add_dram_resources`
was faked to think it had 32 GiB of DRAM installed) and variable MTRR
map includes a WC entry for the framebuffer (and all the RAM):
MTRR: default type WB/UC MTRR counts: 13/9.
MTRR: UC selected as default type.
MTRR: 0 base 0x0000000000000000 mask 0x00003fff80000000 type 6
MTRR: 1 base 0x0000000077000000 mask 0x00003fffff000000 type 0
MTRR: 2 base 0x0000000078000000 mask 0x00003ffff8000000 type 0
MTRR: 3 base 0x0000000090000000 mask 0x00003ffff0000000 type 1
MTRR: 4 base 0x0000000100000000 mask 0x00003fff00000000 type 6
MTRR: 5 base 0x0000000200000000 mask 0x00003ffe00000000 type 6
MTRR: 6 base 0x0000000400000000 mask 0x00003ffc00000000 type 6
MTRR: 7 base 0x0000000800000000 mask 0x00003fff80000000 type 6
MTRR: 8 base 0x000000087fc00000 mask 0x00003fffffc00000 type 0
ADL has 9 variable-range MTRRs, previously 8 of them were used, and
there was no separate entry for the framebuffer, thus leaving the
default MTRR in place of uncached.

From ANX7625 spec, the delay between powering on power supplies and GPIO
should be larger than 10ms. Since it takes about 4ms for the previous
GPIO EN_PP3300_EDP_DX to be pulled up, increase the delay from 2ms to
14ms.

This change is needed to update the option API to use unsigned integers.
The CMOS option system does not support negative numbers.
The volume field is only 8 bits long. Do not set the volume if it is out
of range. Also, use an out-of-range value as fallback to skip setting
the volume when it cannot be read using the option API, to preserve the
current behavior.
