Kefeng Wang 1ff5c8e8c8 Revert "powerpc: Set max_mapnr correctly" ...

This reverts commit 602946ec2f.

If CONFIG_HIGHMEM is enabled, no highmem will be added with max_mapnr
set to max_low_pfn, see mem_init():

  for (pfn = highmem_mapnr; pfn < max_mapnr; ++pfn) {
        ...
        free_highmem_page();
  }

Now that virt_addr_valid() has been fixed in the previous commit, we can
revert the change to max_mapnr.
