Remove arch-specific show_mem() in favor of the generic version.

This also removes the following redundant information display:

- free swap pages, printed by show_swap_cache_info()
- pages in swapcache, printed by show_swap_cache_info()
- dirty pages, writeback pages, mapped pages, slab pages,
  pagetables pages, printed by show_free_areas()

where show_mem() calls show_free_areas(), which calls
show_swap_cache_info().
