m68k: mm: Use table allocator for pgtables
With the new page-table layout, using full (4k) pages for (256 byte)
pte-tables is immensely wastefull. Move the pte-tables over to the
same allocator already used for the (512 byte) higher level tables
(pgd/pmd).
This reduces the pte-table waste from 15x to 2x.
Due to no longer being bound to 16 consecutive tables, this might
actually already be more efficient than the old code for sparse
tables.
