powerpc/mm/radix: remove useless kernel messages
Booting a POWER9 PowerNV system generates a few messages below with
"____ptrval____" due to the pointers printed without a specifier
extension (i.e unadorned %p) are hashed to prevent leaking information
about the kernel memory layout.

radix-mmu: Partition table (____ptrval____)
radix-mmu: Mapped 0x0000000000000000-0x0000000040000000 with 1.00 GiB
