[PATCH v14 0/8] Adds AmdSmmCpuFeaturesLib and MmSaveStateLib

["Abdul Lateef Attar" <abdattar@amd.com>]

Backward-compatibility changes:
  This patch series removes the SmmCpuFeaturesReadSaveStateRegister
  and SmmCpuFeaturesWriteSaveStateRegister interface/function.
  SmmReadSaveState() and SmmWriteSaveState() now directly invokes MmSaveStateLib
  routines to save/restore registers.
