mm: use free_area_init() instead of free_area_init_nodes()

free_area_init() has effectively became a wrapper for
free_area_init_nodes() and there is no point of keeping it.  Still
free_area_init() name is shorter and more general as it does not imply
necessity to initialize multiple nodes.

Rename free_area_init_nodes() to free_area_init(), update the callers and
drop old version of free_area_init().
