powerpc/64s/ptdump: Fix kernel_hash_pagetable dump for ISA v3.00 HPTE format

[ Upstream commit eae40a6da63faa9fb63ff61f8fa2b3b57da78a84 ]

HPTE format was changed since Power9 (ISA 3.0) onwards. While dumping
kernel hash page tables, nothing gets printed on powernv P9+. This patch
utilizes the helpers added in the patch tagged as fixes, to convert new
format to old format and dump the hptes. This fix is only needed for
native_find() (powernv), since pseries continues to work fine with the
old format.
