Introduce the common read_non_pci_resources function to read the base
address of the non-PCI resources within the MMIO regions configured in
the data fabric registers and pass that info to the resource allocator.
Each SoC will need to provide implementations for get_iohc_misc_smn_base
and get_iohc_non_pci_mmio_regs in order for read_non_pci_resources to
know the SoC-specific base addresses, register offsets and MMIO region
sizes. In case of SoCs with only one PCI root domain, the domain
parameter of get_iohc_misc_smn_base will be unused, but in the case of
SoCs with more than one PCI root domains, this parameter will be used by
the SoC-specific code.

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.

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.

BUG=b:247670186
TEST=Verify display over TCSS and its impact on boot time for
google/rex
Time taken by enter_dp_mode / wait_for_dp+hpd / MultiPhaseSiInit
functions with this patch train:
1. When AP Mode entry is enabled
- With type-c display on C1 and SuzyQ on C0: 6.9ms / 420ms / 616ms
- With USB key on C1 and SuzyQ on C0 : 6.0ms / 505ms / 666ms
- Without any device on C1 and SuzyQ on C0 : 3.7ms / 0ms / 178ms
2. When AP Mode entry is disabled
- With type-c display on C1 and SuzyQ on C0: 1.7ms / 2.5ms / 213ms
- With USB key on C1 and SuzyQ on C0 : 0.9ms / 3.3ms / 177ms
- Without any device on C1 and SuzyQ on C0 : 0.8ms / 1.8ms / 165ms
Without this patch train, wait_for_hpd would cause a constant delay of
WAIT_FOR_HPD_TIMEOUT_MS (i.e. 3 seconds) per type-c port when there is
no device connected.

Because of the way that the CBFS filename is generated from the contents
of the microcode patch, if a duplicate microcode patch is included in
the build, the makefile would create a second copy of the name, which
doesn't work. This led to "odd" results where the other attributes of
the first copy were erased, causing cbfstool to fail. The cause of the
failure is not immediately obvious, and is a little difficult to track
down.
This patch causes an immediate failure and gives a reason as to the
cause of the issue.
When a failure is seen, this is the result:
File1: 3rdparty/amd_blobs/phoenix/psp/TypeId0x66_UcodePatch_PHXn4_A0.bin
File2: 3rdparty/amd_blobs/phoenix/psp/TypeId0x66_UcodePatch_PHX4_A0.bin
src/soc/amd/common/block/cpu/Makefile.inc:25: *** Error: The cbfs
filename "cpu_microcode_a740.bin" is used for both above files. Check
your microcode patches for duplicates.. Stop.
TEST=Now checked for both positive and negative failures.

There is a data abort in ABL when the memory training data is used from
APOB Cache. Disable APOB Cache until the cause is identified. The
downside of this change is that the memory training happens in every
boot cycle.

The PCR (Private Configuration Register) is applicable to access the
P2SB register space starting with the Intel SkyLake generation of SoC.
Prior to Intel Meteor Lake SoC generation, the only P2SB existed inside
the PCH die. Starting with Meteor Lake SoC, there are two P2SB, one in
SoC die (same as PCH die for U/H SoC) and another in IOE die.
This patch renames pcr.asl to pch_pcr.asl to reflect the actual source
of the P2SB IP in the die (i.e., SoC die or PCH die).
