In the same spirit as already done in pte query helpers,
this patch changes pte setting helpers to perform endian
conversions on the constants rather than on the pte value.
In the meantime, it changes pte_access_permitted() to use
pte helpers for the same reason.

nohash/64 only uses book3e PTE flags, so it doesn't need pte-common.h
This also allows to drop PAGE_SAO and H_PAGE_4K_PFN from pte_common.h
as they are only used by PPC64

is no exec protection, so pte_mkexec() and
pte_exprotect() are nops and pte_exec() returns always true.

Implement it on PPC as well in order to avoid drivers using

Now the pte-common.h is only for nohash platforms, lets
move pte_user() helper out of pte-common.h to put it
together with other helpers.

_PAGE_NO_CACHE is a platform specific flag. In addition, this flag
is misleading because one would think it requests a noncached page
whereas a noncached page is _PAGE_NO_CACHE | _PAGE_GUARDED
_PAGE_NO_CACHE alone means write combined
