powerpc/mm: move setting pte specific flags to pfn_pte
powerpc used to set the pte specific flags in set_pte_at(). This is
different from other architectures. To be consistent with other
architecture update pfn_pte to set _PAGE_PTE on ppc64. Also, drop now
unused pte_mkpte.
We add a VM_WARN_ON() to catch the usage of calling set_pte_at() without
setting _PAGE_PTE bit. We will remove that after a few releases.
With respect to huge pmd entries, pmd_mkhuge() takes care of adding the
_PAGE_PTE bit.
[akpm@linux-foundation.org: whitespace fix, per Christophe]
