[MIPS] prom_free_prom_memory cleanup
Current prom_free_prom_memory() implementations are almost same as free_init_pages(), or no-op. Make free_init_pages() extern (again) and make prom_free_prom_memory() use it. Signed-off-by: Atsushi Nemoto <anemo@mba.ocn.ne.jp> Signed-off-by: Ralf Baechle <ralf@linux-mips.org>
