sparc32: use pgtable-nopud instead of 4level-fixup

32-bit version of sparc has three-level page tables and can use
pgtable-nopud and folding of the upper layers.

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