iommu/amd: Introduce PPR_TAG_LAST_PAGE() macro
The PPR tag field (PPRtag) encodes two distinct fields: the 9-bit tag
value (bits 8-0) and the last-page indicator L bit (bit 9).
Fix PPR_TAG() to mask only the 9-bit tag field and introduce
PPR_TAG_LAST_PAGE to explicitly extract the L bit. This way it becomes
easy to read.
