iommu/arm-smmu: correct the physical address mask during ATOS
We're currently taking the upper 52 bits from the CB_PAR register and
using them for the output physical address. That doesn't make sense for
a few reasons, not the least of which is the fact that physical
addresses are only 48 bits on ARM64 and even less on ARM32. Also, when
using V7L and V8 descriptor formats the top byte of the CB_PAR register
contains the memory attributes for the translation. Fix this by masking
out everything above the valid physical address bits with PHYS_MASK.
