Suravee Suthikulpanit 9dd299d8c6 iommu/amd: Introduce global variable for storing common EFR and EFR2 
Some IOMMU features require that all IOMMUs must support the feature,
which is determined by checking the support bit in the Extended Feature
Register 1 and 2 (EFR/EFR2) on all IOMMUs. This check is done by the
function check_feature_on_all_iommus(), which iterates through all
IOMMUs everytime it is called.

Instead, introduce a global variable to store common EFR/EFR2 among all
IOMMUs. In case of inconsistent EFR/EFR2 masks are detected on an IOMMU,
a FW_BUG warning is reported.
