Hello Fred Reitberger, Jason Glenesk, Matt DeVillier, build bot (Jenkins), ritul guru,

soc/amd/common/smi_util: add PSP SMI helper functions

The PSP can send SMIs to the x86 side of the system. Add helper
functions to configure and to reset the PSP SMI generation. Since
Stoneyridge also selects SOC_AMD_COMMON_BLOCK_SMI, add the SMITRIG0_PSP
define and rename SMITYPE_FCH_FAKE0 to SMITYPE_PSP in its SoC-specific
smi.h to bring it in line with the newer SoCs.

This patch is split out from CB:65523.
