Introduce huge pte versions of pte_page, pte_present and pte_young.

This allows ARM (without LPAE) to use alternative pte processing logic
for huge ptes.

Generic implementations that call the standard pte versions are also
added to asm-generic/hugetlb.h.

Changed in V2 - moved from #ifndef,#define macros to entries in
asm-generic/hugetlb.h as it makes more sense to have these with the
other huge_pte_. definitions.

The only other architecture I can see that does not use
asm-generic/hugetlb.h is s390. This patch includes trivial definitions
for huge_pte_{page,present,young} for s390.

I've compile-tested this for s390, but don't have one under my desk so
have not been able to test it.

Hello,
I was just wondering if this patch looked reasonable to people?

Cheers,
