[ARM] rationalize memory configuration code some more
Currently there are two instances of struct meminfo: one in
kernel/setup.c marked __initdata, and another in mm/init.c with
permanent storage. Let's keep only the later to directly populate
the permanent version from arm_add_memory().
Also move common validation tests between the MMU and non-MMU cases
into arm_add_memory() to remove some duplication. Protection against
overflowing the membank array is also moved in there in order to cover
the kernel cmdline parsing path as well.
