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

This also removes the following redundant information display:

- free pages, printed by show_free_areas()
- pages in swapcache, printed by show_swap_cache_info()

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