soc/amd/common/cpu: Add Kconfig to program the PSP_ADDR MSR

The PSP_ADDR_MSR is programmed into the BSP by FSP, but not always
propagated to the other cores/APs. Add a hook to run a function
which will read the MSR value from the BSP, and program it into the
APs, guarded by a Kconfig. SoCs which wish to utilize this feature
can select the Kconfig.
