powerpc/book3s64/radix: Add H_RPT_INVALIDATE pgsize encodings to mmu_psize_def
Add a field to mmu_psize_def to store the page size encodings
of H_RPT_INVALIDATE hcall. Initialize this while scanning the radix
AP encodings. This will be used when invalidating with required
page size encoding in the hcall.
