Currently there are 3 GDTs (Global Descriptor Tables) being used on x86:
- preRAM (gdt_init.S)
- SMM (smm_stub.S)
- RAM (c_start.S)
They have different layouts and thus different offsets for the segments
being used in assembly code. Stop using different GDT segments and
ensure that for ROM (preRAM + SMM) and RAM (ramstage) the segments
match. RAM will have additional entries, not found in pre RAM GDT,
but the segments for protected mode and 64-bit mode now match in
all stages.
This allows to use the same defines in all stages. It also drops the
need to know in which stage the code is compiled and it's no longer
necessary to switch the code segment between stages.
While at it fix the comments in the ramstage GDT and drop unused
declarations from header files, always set the accessed bit and drop
GDT_CODE_ACPI_SEG.

Some of MTK's ICs (such as the MT8189) use two eFuse registers to
record CPU ID information.
Users can use get_cpu_id and get_cpu_segment_id to obtain the SoC
version. For example, the CPU ID of the MT8189H is 0x81890000, and
the CPU segment ID is 0x21.

This commit addresses a performance issue on the Panther Lake H SoC by
disabling the EnableFastVmode setting in addition to the CepEnable
setting. It was discovered that merely disabling CepEnable was
insufficient, as the FSP continued to program Panther Lake U IccLimit on
FastVMode capable boards, causing performance degradation under
high-stress conditions. By also disabling EnableFastVmode, the I_TRIP
value is prevented from being set lower than the device's actual
capability.
TEST=Verify that IccLimit is programmed with FSP default values.

Hook up `Device4Enable` FSP setting to devicetree state and drop its

register setting and PCI device status are not in agreement, use
the register setting to determine the PCI device status, since that
is what FSP uses.

Some mainboards use the common DPTF ASL rather than the DPTF chip
driver, and those boards need to skip generation of the TCPU ACPI
device in order to avoid a duplicate being created and causing
issues with ACPI table parsing. Create a Kconfig that affected
boards will select to skip generating the TCPU in the SSDT.

The GNU assembler allows to use arithmetics on constant expression,
except for division using the '/' character. By default the '/'
introduces a line comment, see [1]. This behaviour can be changed when
the command line argument --divide is being used. However that's not
the case for coreboot.
Since the divide doesn't work as expected the assembler generates 512
times as much instructions on the .rept evaluation than it should. This
didn't cause any problem since it only filled PML4E, but the additional
entries pointed to non existing PDPTs. As long as the memory above 512GB
wasn't accessed it worked just fine.
Use shifts to fix the arithmetic and thus generate only the expected
number of page table entries. Required for the following patch, which
walks page tables and expects to find sane directories.

Reducing the IGD stolen memory allocation from 128MB to 64MB
significantly optimizes system memory resource utilization (by 64MB).
Furthermore, this reduction frees one MTRR. Previously, the 128MB IGD
allocation consumed all 10 available BIOS MTRRs; the new 64MB allocation
now leaves MTRR index 9 available.
