Code that requires memory banks to be registered, thus has to use mmu_initcall(), but this is not possible for code that reliably needs to run before MMU init: We need to give board code and device tree parsing code the chance to reserve_sdram_region parts of SDRAM that contain secure firmware to avoid speculative execution into them once the MMU is turned on. For this reason, define a new postmem_initcall() level and already use it for add_mem_devices, which has nothing to do with mmu_initcall. Another user that can't be mmu_initcall() will follow in a later commit.
