init: define new postmem_initcall()
Memory banks are added in mem_initcall() and are used in mmu_initcall()
which directly follows it to set caching attributes for the banks.
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.
