mm: always define pxx_pgprot()
There're:
- 8 archs (arc, arm64, include, mips, powerpc, s390, sh, x86) that
support pte_pgprot().
- 2 archs (x86, sparc) that support pmd_pgprot().
- 1 arch (x86) that support pud_pgprot().
Always define them to be used in generic code, and then we don't need to
fiddle with "#ifdef"s when doing so.
