Subject: [PATCH] of: fdt: Remove early_init_dt_reserve_memory_arch() override
capability
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.
