The remaining (active) binaryPI boards moved away from
BINARYPI_LEGACY_WRAPPER and have POSTCAR_STAGE now.
As the cache_as_ram.S is also used with AGESA, this slightly
reduces the codesize there for romstage and postcar as well.
This commit is actually a revert for the vendorcode parts,
AMD originally shipped the codes using 'invd' for the CAR
teardown, but these were changed for coreboot due the
convoluted teardown that used to happen with non-empty stack.

As per the 4.11 release requirement, CAR_GLOBAL_MIGRATION=n is a
mandatory feature, which most binaryPI boards lack as they
use BINARYPI_LEGACY_WRAPPER.
Disable all binaryPI platforms, except pcengines/apu2, from
the build for the time being. If a platform does not reach
POSTCAR_STAGE=y and C_ENVIRONMENT_BOOTBLOCK=y within a
reasonable timeframe both the mainboard and the respective
unused platform support code will get removed.

Adopting the mainboard code to use hooks from state_machine.h.
No post codes are changed, except for those which were explicitly sent in
mainboard/romstage.c. Boot time is reduced by more than 7%, from 5.029s to
4.657s (coreboot timestamps, measured for loglevel 7).
POSTCAR_STAGE is required since coreboot 4.11 release.

It is a requirement for Firmware to have Firmware Interface Table (FIT),
which contains pointers to each microcode update.
The microcode update is loaded for all logical processors before reset vector.
FSPT_UPD.MicrocodeRegionBase and FSPT_UPD.MicrocodeRegionLength are
input parameters to TempRamInit API.
If these values are 0, FSP will not attempt to update microcode.
Since Gen-4 all IA-SoC has FIT loading ucode even before cpu reset in place
hence skipping FSP-T loading ucode after CPU reset options.
Also removed unused kconfig CONFIG_CPU_MICROCODE_CBFS_LOC and
CONFIG_CPU_MICROCODE_CBFS_LEN

When we only enable XO_SOC and mask most BBLPM requests, the BBLPM HW

Under BBLPM mode, inaccurate(about 1.5KHz offset) 26MHz clocks from

Current code uses CPUID leaf 0x1, EBX bits 16:23 to determine number for
"core count". However, it turns out this number has little to do with
real number of cores. According to SDM vol 2A, it stays for "maximum
number of addressable IDs for logical processors in this physical
package". This does not seem to take into account fusing of giving
processor.
The new code determines 'core count' by dividing thread-level cpus by
reported logical cores. This seems to be the only way to arrive
to number of cores as it is reported in official CPU datasheet.
