Revert "nios2: Convert __pte_free_tlb() to use ptdescs"

This reverts commit 6ebe94b.

The patch "nios2: Convert __pte_free_tlb() to use ptdescs" was supposed
to go together with a patchset that Vishal Moola had planned taking it
through the mm tree. By just having this patch, all NIOS2 builds are
broken.
