Start moving code that is generic between radix and hash to book3s64
specific headers from the book3s64 hash specific one.

pmd_hugepage_update() is inside #ifdef CONFIG_TRANSPARENT_HUGEPAGE. THP
can only be enabled if PPC_BOOK3S_64=y && PPC_64K_PAGES=y, aka. hash64.
On hash64 we always define PTE_ATOMIC_UPDATES to 1, meaning the #ifdef
in pmd_hugepage_update() is unnecessary, so drop it.
That is also the only use of PTE_ATOMIC_UPDATES in any of the hash code,
meaning we no longer need to #define it at all in the hash headers.
Note it's still #defined and used in the nohash code.

functions which operate on pte bits are moved to hash*.h and other
generic functions are moved to pgtable.h

We convert them static inline function here as we did with pte_val in
the previous patch

We also move __ASSEMBLY__ towards the end of header. This avoid
having #ifndef __ASSEMBLY___ all over the header

In this patch we do:
cp pgtable-ppc32.h book3s/32/pgtable.h
cp pgtable-ppc64.h book3s/64/pgtable.h
This enable us to do further changes to hash specific config.
We will change the page table format for 64bit hash in later patches.
