Naming a device allows an ACPI _ROM method to be written for it. GPUs
may require this to make the configuration data contained within
available to an OS driver. This may be required for GPUs that do not
contain their vBIOS, or perhaps the drivers require it in this form/fashion.
Working on an Acer Aspire VN7-572G (Skylake-U). nouveau successfully
obtains the vBIOS via ACPI (kernel 5.7.11).

Tested with 2560p, which still works without problems, and the TPM can

Two of the items in the FADT ACPI table frequently are partially board-
specific, so let's make it easy to update them via devicetree settings.
- fadt_boot_arch 0="legacy free" which while reasonable, probably isn't
what will be wanted by most mainboards, so this should generally get
updated in the specific devicetree.
- In fadt_flags all chipset-specific flags get set while the mainboard
has to set all other flags that it needs to have set.
This patch changes the default for fadt_boot_arch.

Xeon-SP Skylake Scalable Processor can have 36 CPU threads (18 cores).
Current coreboot SMM is unable to handle more than ~32 CPU threads.
This patch introduces a version 2 of the SMM module loader which
addresses this problem. Having two versions of the SMM module loader
prevents any issues to current projects. Future Xeon-SP products will
be using this version of the SMM loader. Subsequent patches will
enable board specific functionality for Xeon-SP.
The reason for moving to version 2 is the state save area begins to
encroach upon the SMI handling code when more than 32 CPU threads are
in the system. This can cause system hangs, reboots, etc. The second
change is related to staggered entry points with simple near jumps. In
the current loader, near jumps will not work because the CPU is jumping
within the same code segment. In version 2, "far" address jumps are
necessary therefore protected mode must be enabled first. The SMM
layout and how the CPUs are staggered are documented in the code.
By making the modifications above, this allows the smm module loader to
expand easily as more CPU threads are added.
TEST=build for Tiogapass platform under OCP mainboard. Enable the
following in Kconfig.
select CPU_INTEL_COMMON_SMM
select SOC_INTEL_COMMON_BLOCK_SMM
select SMM_TSEG
select HAVE_SMI_HANDLER
select ACPI_INTEL_HARDWARE_SLEEP_VALUES
Debug console will show all 36 cores relocated. Further tested by
generating SMI's to port 0xb2 using XDP/ITP HW debugger and ensured all
cores entering and exiting SMM properly. In addition, booted to Linux
5.4 kernel and observed no issues during mp init.

This changes the logic of the code, since it configures PegxEnable
before the if-blocks, where x is the number of the PEG device, and the
further configuration of the PEG devices depends on the enablement of
PegxEnable.
