m68k/mm: motorola - Add missing initialization of max_pfn
If max_pfn is not initialized, the various /proc/kpage* files are empty, and selftests/vm/mlock2-tests will fail. max_pfn is also used by the block layer to calculate DMA masks. Signed-off-by: Geert Uytterhoeven <geert@linux-m68k.org> Acked-by: Greg Ungerer <gerg@uclinux.org>
