Suravee Suthikulpanit 7d7d38afb3 iommu/amd: Adding Extended Feature Register check for PC support
The IVHD header type 11h and 40h introduce the PCSup bit in
the EFR Register Image bit fileds. This should be used to
determine the IOMMU performance support instead of relying
on the PNCounters and PNBanks.

Note also that the PNCouters and PNBanks bits in the IOMMU
attributes field of IVHD headers type 11h are incorrectly
programmed on some systems.

So, we should not rely on it to determine the performance
counter/banks size. Instead, these values should be read
from the MMIO Offset 0030h IOMMU Extended Feature Register.
