[POWERPC] Add hugepagesz boot-time parameter
This adds the hugepagesz boot-time parameter for ppc64. It lets one pick the size for huge pages. The choices available are 64K and 16M when the base page size is 4k. It defaults to 16M (previously the only only choice) if nothing or an invalid choice is specified. Tested 64K huge pages successfully with the libhugetlbfs 1.2.
