AMD CPUs have a convenient MSR that allows to set the SMBASE in the save
state without ever entering SMM (e.g. at the default 0x30000 address).
This has been a feature in all AMD CPUs since at least AMD K8. This
allows to do relocation in parallel in ramstage and without setting up a
relocation handler, which likely results in a speedup. The more cores
the higher the speedup as relocation was happening sequentially. On a 4
core AMD picasso system this results in 33ms boot speedup.
TESTED on google/vilboz (Picasso) with CONFIG_SMI_DEBUG: verify that SMM
is correctly relocated with the BSP correctly entering the smihandler.

Thermal configuration registers are now located behind PMC PWRMBASE
for MeteorLake as well (same as ADL). Hence, using thermal common code
to sets the thermal low threshold as per mainboard provided
`pch_thermal_trip`.
Note: These thermal configuration registers are RW/O hence, setting
those early prior to FSP-S helps coreboot to set the desired low
thermal threshold for the platform.
TEST=Dump thermal configuration registers PWRMBASE+0x150c etc on
Google/rex prior to FSP-S shows that registers are now programmed
based on 'pch_thermal_trip' and lock register BIT31 is set.
