AGESA S3 restore needs to occur before SMM finalization/locking,
but it's a crapshoot as to which runs first since both use the same
BS_OS_RESUME/BS_ON_ENTRY boot state callback, and there's no way
to prioritize/force ordering.
To work around this, move the AGESA S3 resume call to the preceding
boot state (BS_OS_RESUME_CHECK) to ensure it runs first, and guard it
to ensure it only runs on the S3 resume path.

This supports a brand new I2C driver that is designed specifically
for the Pixel 2013 chromebook (LINK). The GMBus interface on the IGPU
is an i2c-compatible interface, but AFAIK only Link has touch devices
attached in this way.
On Windows, the PCIe device for the IGP is owned by the Intel
proprietary driver, hence a separate ACPI device has to be added for
the I2C driver arbitrator to attach to. The MMIO method is used instead
of _CRS so that Windows does not try to assign ownership of the
resource to our device (even though we're using the MMIO registers at
the same time as the IGP driver).
Even though in theory 2 drivers accessing the same MMIO may cause
problems, in testing, there has been no issues with
sleep/wake/hibernate, updating/installing/uninstalling the IGP driver,
or changing display resolutions with the i2c driver attached.
The arbitrator is necessary as well, since even though there are
multiple i2c buses, the MMIO registers are shared. Hence a shared lock
is required for i2c access across the buses.
The original Sleep Button devices are preserved for Linux due to the
completely custom and non-standard implementation of the Windows driver
in order to work around the non-standard nature of Link's hardware.

From the Linux documentation (Documentation/PCI/acpi-info.rst):
[6] PCI Firmware 3.2, sec 4.1.2:
If the operating system does not natively comprehend reserving the
MMCFG region, the MMCFG region must be reserved by firmware. The
address range reported in the MCFG table or by _CBA method (see Section
4.1.3) must be reserved by declaring a motherboard resource. For most
systems, the motherboard resource would appear at the root of the ACPI
namespace (under \_SB) in a node with a _HID of EISAID (PNP0C02), and
the resources in this case should not be claimed in the root PCI bus’s
_CRS. The resources can optionally be returned in Int15 E820 or
EFIGetMemoryMap as reserved memory but must always be reported through
ACPI as a motherboard resource.
So in order for the OS to use ECAM MMCONF over legacy PCI IO
configuration, a PNP0C02 HID device needs to reserve this region.
As no AMD platform has this defined in DSDT this fixes Linux using
legacy PCI IO configuration over MMCONF. Tianocore messes with e820
table in such a way that it prevents Linux from using PCIe ECAM. This
change fixes that problem.

Disable the CSME by default now that S3 is used instead of S0ix.
The CSME will not go into a low power state during S0ix when it is
disabled. This prevents the CPU from reaching C10 and so increases the
power usage during suspend compared to leaving CSME enabled. (This was
measured to be a ~2W different on TGL-U.) In S3, the state of the CSME
doesn't matter because the CPU will be off.

Update the code to iterate over sockets until PlatformData.numofIIO

This patch creates a helper library to migrate all the common P2SB
access routines. The PCH P2SB ACPI implementation will now rely on the
common library to perform PCR read/write operations. This will make the
code more modular and easier to maintain.
The helper library provides a single interface for accessing P2SB
registers. This makes it easier to port the code to different platforms,
for example: adding support for PS2B belongs to the IOE die for
Meteor Lake SoC generation.
