Fix an off-by-one error in the definition of AMDVI_IR_PHYS_ADDR_MASK. The current definition masks off the most significant bit of the Interrupt Table Root ptr i.e. it only generates a mask with bits [50:6] set. See the AMD I/O Virtualization Technology (IOMMU) Specification for the Interrupt Table Root Pointer[51:6] field in the Device Table Entry format.
