ARM: i.MX8M: include only necessary ddrphy firmwares in image

So far we always include ddrphy firmwares for DDR4 and LPDDR4 in the
images. Pass the DDR type to the RAM controller initialization so
that the type is known at compile time. With this the compiler can
discard the unused firmware files.
