AMD's Windows display drivers validate the checksum of the VBIOS data
in the VFCT table (which gets modified by the FSP GOP driver), so
ensure it is set correctly after copying the VBIOS into the table if the
FSP GOP driver was run. Without the correct checksum, the Windows GPU
drivers will fail to load with a code 43 error in Device Manager.
Thanks to coolstar for root causing the issue.
TEST=build/boot Win11 on google/skyrim (frostflow), ensure GPU driver
loaded and functional.

Allow the use of 64bit MMCONF base in MCFG table.
Previously only 32 bits were utilized for MMCONF base, while the
remaining 32bits were reserved & held value of zero as evident from MCFG
table disassembly. This commit entails updating the 'base_address' field
in the 'mmconfig' structure to 64 bits and removing the 'base_reserved'
field.

According to ACPI Release 6.5 systems supporting PIC (i8259)
interrupt mechanism need to report IRQ vector for the SCI_INT
field. In PIC mode only IRQ0..15 are allowed hardware vectors.
This change should cover section 5.2.9 to not pass SCI_INT
larger than IRQ15. Section 5.2.15.5 needs follow-up work.
Care should be taken that ioapic_get_sci_pin() is called
after platform code has potentially changed the routing
from the default.
It appears touched all platforms except siemens/mc_aplX
currently program SCI as IRQ9.

Implement sub-function 1 (Get Device Constraints)
of the Low Power S0 Idle Device-Specific Method (_DSM).
This provides a way in which to describe various devices required
D-states to enter LPM (S0ix). The information can be used to help
in diagnostics and understanding of S0ix entry failure.
Values were derived from Intel document 595644 (rev 0.45) and
the ADL FSP sample ASL.
This implementation adds support for ADL. Other SoC's could be
ported to be included as well. If they aren't, they will default
to the existing behavior of a single hardcoded device to ensure
compatibility with Windows.

The ACPI RSDP can only be found in:
- legacy BIOS region
- via UEFI service
On some systems like ARM that legacy BIOS region is not an option, so
to avoid needing UEFI it makes sense to expose the RSDP via a coreboot
table entry.
This also adds the respective unit test.
