alpha: use pgtable-nopud instead of 4level-fixup

Patch series "mm: remove __ARCH_HAS_4LEVEL_HACK", v13.

These patches convert several architectures to use page table folding
and remove __ARCH_HAS_4LEVEL_HACK along with
include/asm-generic/4level-fixup.h.

For the nommu configurations the folding is already implemented by the
generic code so the only change was to use the appropriate header file.

As for the rest, the changes are mostly about mechanical replacement of
pgd accessors with pud/pmd ones and the addition of higher levels to
page table traversals.

With Vineet's patches from "elide extraneous generated code for folded
p4d/pud/pmd" series [1] there is a small shrink of the kernel size of
about -0.01% for the defconfig builds.

This patch (of 13):

It is not likely alpha will have 5-level page tables.

Replace usage of include/asm-generic/4level-fixup.h and implied
__ARCH_HAS_4LEVEL_HACK with include/asm-generic/pgtable-nopud.h and
adjust page table manipulation macros and functions accordingly.
