microblaze: use pgtable-nopmd instead of 4level-fixup
microblaze has only two-level page tables and can use pgtable-nopmd and
folding of the upper layers.
Replace usage of include/asm-generic/4level-fixup.h and explicit
definition of __PAGETABLE_PMD_FOLDED in microblaze with
include/asm-generic/pgtable-nopmd.h and adjust page table manipulation
macros and functions accordingly.
