Aneesh Kumar K.V 92d9dfda8b powerpc/mm/4k: Limit 4k page size config to 64TB virtual address space
Supporting 512TB requires us to do a order 3 allocation for level 1 page
table (pgd). This results in page allocation failures with certain workloads.
For now limit 4k linux page size config to 64TB.

Fixes: f6eedbba7a ("powerpc/mm/hash: Increase VA range to 128TB")
