driver/amd/opensil: Add PHX OpenSIL POC TP2/TP3 calls

Call OpenSIL timepoint 2 for further initialization of AMD SoC after
coreboot has performed PCIe enumeration, and timepoint 3 for late SoC
IPs programming and register locking closer to payload load prior to OS
handoff. For future refactors, other generic OpenSIL calls from
vendorcode/src/amd/opensil may be moved into the driver directory as
well.
