Removed the use of MAP_HUGETLB for anonymous mapping on ppc64. The
MAP_HUGETLB had previously been added to workaround issues on IBM Power8
systems when mapping /dev/zero (see: commit
284ae3e9ff9a92575c28c858efd2c85c8de6d440). In the current code the
MAP_HUGETLB flag will cause the anonymous mapping to fail on Power9.
Note, Power8 is currently failing to correctly mmap Hugepages, with and
without this change.

The changes are contained entirely to POWER9 code paths/docs, so while i
cannot verify them working for obvious reasons, i have no objections to
this patch.
