At the moment we destroy the DTB mappings we have in setup_pagetables and we restore them only in setup_mm. Move setup_mm right after setup_pagetables. This ensures we have a valid DTB mapping while running the subsequent initialization code. Changes in v5: - reword commit message; - turn printk in setup_mm into an early_printk.
