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