Commit c7b8809f155a ("soc/amd/common/block/gfx: Use TPM-stored hash
for vbios cache validation") replaced checking the vbios signature
(first two bytes) with checking against a TPM-stored hash, but there
exists an edge case where the empty cache can be hashed and therefore
never updated with the correct vbios data. To mitigate this, re-add
the signature check to ensure that an empty cache will never be hashed
to TPM.
BUG=b:255812886
BRANCH=skyrim
TEST=build/boot skyrim w/selective GOP enabled, flash full firmware
image, ensure GOP driver is run until cache updated with valid data
and hashed to TPM.

PCIe bridges need to provide the LTR (latency tolerance reporting)
maximum snoop/non-snoop values so that they are inherited by downstream
PCIe devices which support and enable LTR. Without this, downstream
devices cannot have LTR enabled, which is a requirement for supporting
PCIe L1 substates. Enabling L1ss without LTR has unpredictable behavior,
including some devices refusing to enter L1 low power modes at all.
Program the max snoop/non-snoop latency values for all PCIe bridges
using the same value used by AGESA/FSP, 1.049ms.

All AMD SoCs with Zen-based CPU cores are already using timestamps based
on the TSC counter, so use the existing common infrastructure instead of
reimplementing it in a similar way.
The behavior of the code changes slightly, but results in identical
timestamps. The timestamp_get implementation in soc/amd/common/block/cpu
divided the result of rdtscll() in timestamp_get by the result of
tsc_freq_mhz() and didn't override the weak timestamp_tick_freq_mhz
implementation that returns 1. The non AMD specific code returns the
result of rdtscll() in timestamp_get, but returns tsc_freq_mhz() instead
of 1 in timestamp_tick_freq_mhz, so we still get the correct timestamps.
TEST=The raw timestamps printed on the serial console are now multiplied
by the expected factor of the TSC frequency in MHz.
TEST=Normalized timestamps printed on the serial console by the x86 code
don't change significantly on Mandolin when comparing before and after
this patch. A slight variation in the timestamps is expected. An example
would be:
Before: CPU_CLUSTER: 0 init finished in 630 msecs
After: CPU_CLUSTER: 0 init finished in 629 msecs
TEST=The calculations of the time spent in verstage on PSP before
entering the bootblock on Guybrush result in similar times when
multiplying the value before the patch with the TSC frequency in the
case with the patch applied. The raw values printed on the serial
console by the verstage on PSP use the 1us time base, but the timestamp
logs that end up in CBMEM will be fixed up to use the same time base as
the x86 part of coreboot.

are two differences to the binaryPI SSDT: Now coreboot includes the C1
state in the _CST package instead of just having the kernel add this due
to the ACPI_FADT_C1_SUPPORTED bit being set and the address of the
