iommu/amd: Change rlookup, irq_lookup, and alias to use kvalloc()

This is just CPU memory used by the driver to track things, it doesn't
need to use iommu-pages. All of them are indexed by devid and devid is
bounded by pci_seg->last_bdf or we are already out of bounds on the page
allocation.

Switch them to use some version of kvmalloc_array() and drop the now
unused constants and remove the tbl_size() round up to PAGE_SIZE multiples
logic.
