Commit e7ae8d174eec0b3b ("MIPS: replace add_memory_region with
memblock") removed the last architecture-specific override of
early_init_dt_reserve_memory_arch().
Convert the common implementation from a weak global function to a
static function.

Should the "_arch" suffix be removed?
Similar commit 0fa1c579349fdd90 ("of/fdt: use memblock_virt_alloc for
early alloc") did not.
