Subject: ppc64: increase MAX_PHYSMEM_BITS to 128TB
Upstream: no, adapts the below upstream commit for SLE15 SP1
Git-commit: 599a6579aa916df7800f8e889d68e4287e4520dd

With Linux 4.19-rc1 commit 7d4340bb92a9df78e6e28152f3dd89d9bd82146b,
titled "powerpc/mm: Increase MAX_PHYSMEM_BITS to 128TB with
SPARSEMEM_VMEMMAP config", the PPC64 MAX_PHYSMEM_BITS value has been
bumped up to 47.  The appropriate update has been made in this patch.

[note: apply on 4.12+ for SLE 15 SP1 - incompatible with SLE 15 SP0]
