b0d1cb59c7 UefiCpuPkg/AmdSmmCpuFeaturesLib: Skip SMBASE configuration 
This patch is to avoid configure SMBASE if SmBase relocation has been
done. If gSmmBaseHobGuid found, means SmBase info has been relocated
and recorded in the SmBase array. No need to do the relocation in
SmmCpuFeaturesInitializeProcessor().
