[POWERPC] Remove use of 4level-fixup.h for ppc32

For 32-bit systems, powerpc still relies on the 4level-fixup.h hack,
to pretend that the generic pagetable handling stuff is 3-levels
rather than 4.  This patch removes this, instead using the newer
pgtable-nopmd.h to handle the elision of both the pud and pmd
pagetable levels (ppc32 pagetables are actually 2 levels).

This removes a little extraneous code, and makes it more easily
compared to the 64-bit pagetable code.
