[patch 12/22 -v2] mips: Use generic show_mem()

[hannes]

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

This also removes the following redundant information display:

	- pages in swapcache, printed by show_swap_cache_info()

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

And show_mem() does now actually print something on configurations
with multiple nodes.
