hppa: Add MAP_HUGETLB and MAP_STACK defines [BZ #19285]
The attached patch adds some upstream defines like MAP_HUGETLB and MAP_STACK
in mman.h for the hppa architecture.

The existing MADV_xxK_PAGES defines were dropped upstream, because they were
originally added many years ago based on a proposed patch for the Linux kernel
which was never applied. So, this patch drops those unneeded defines.
