After fixing TPM logs clobbering other regions in CB:73297, S3 no longer
causes cache issues resulting in power off after multiple suspends.
This is required for disabling Intel CSME by default.

The preram TPM log was being copied to the end of the CBMEM TPM log no
matter what the size of the CBMEM TPM log was. Eventually, it would
overwrite anything else in CBMEM beyond the TPM log.
This can currently be reproduced by enabling TPM_MEASURED_BOOT and
performing multiple S3 suspends, as coreboot is incorrectly performing
TPM measurements on S3 resume.

The original default, minimum abbreviated hash length was 7. It dif-
fers on newer systems, however. This breaks reproducibility, so set
an explicit length. 12 hex digits should be good enough.
Note: This sets only a minimum. With a high enough number of commit
objects in the repository, Git could still decide to use a longer
hash, again breaking reproducibility. 12 digits will hopefully pro-
vide enough margin.

The current Sapphire Rapids code assumes that all sockets have working
CPUs. On multi-socket platforms a CPU might be missing or was disabled
due to an error. The variable PlatformData.numofIIO and the variable
SystemStatus.numCpus reflect the working CPUs, but not the actual
socket count.
Update the code to iterate over sockets until PlatformData.numofIIO
IIOs have been found. This is required as FSP doesn't sort IIOs by
working/non working status.
This resolves invalid ACPI table generation and it fixes a crash
as commands were sent to a disabled CPU.
TEST: Disabled Socket1 on IBM/SBP1.

Use the FSP define to iterate over all sockets as the runtime value of
numofIIO is the detected number of sockets, not the highest working
socket.
This fixes printing the HOB on multi-socket platforms where a CPU has
been removed or has been disabled (4S system running as 3S).

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.

rv32iafc-ilp32 is compatible with rv32iac-ilp32 for library
implementation, so add a reuse rule allowing the default configuration
to support rv32iafc.
-IAFC is an unusual configuration (much less common than -IMAFC),
but multilib reuse has essentially no cost: this change is useful to
users of platforms that support hardware floating-point but cannot
use hardware multiply/divide for any reason. To avoid generating a
new set of libraries this is limited to the soft-float ABI.
Tested by verifying that `gcc -march=rv32iafc -mabi=ilp32
--print-search-dirs` refers to the rv32iac/ilp32 library directory
as expected, rather than just the root library directory as occurs
when an unsupported target is selected (for instance, rv32id).
