[PATCH 1/2 v4] Fix compile issue with hugepage_sz in 32-bit system

[Michael Qiu <michael.qiu-ral2JQCrhuEAvxtiuMwx3w@public.gmane.org>]

lib/librte_eal/linuxapp/eal/eal_memory.c:324:4: error: comparison
is always false due to limited range of data type [-Werror=type-limits]
    || (hugepage_sz == RTE_PGSIZE_16G)) {
    ^
cc1: all warnings being treated as errors

This was introuduced by commit b77b5639:
        mem: add huge page sizes for IBM Power

The root cause is that size_t is 32-bit in i686 platform,
but RTE_PGSIZE_16M and RTE_PGSIZE_16G are always 64-bit.

Force hugepage_sz to always 64-bit to avoid this issue.

---
 v4 ---> v3
	Change hugepage_sz from size_t to uint64_t
	split second bugfix to another patch

 v3 ---> v2
	Change RTE_PGSIZE_16G from ULL to UL
	to keep all entries consistent

 V2 ---> v1
	Change two type entries to one, and
	leave RTE_PGSIZE_16G only valid for
	64-bit platform
