[PATCH 4/8] MIPS: make use of merged defconfigs

QEmu's Malta emulation can be used in four flavors depending on
endianness and CPU register width. So far we only had two defconfigs and
expected users to adjust the config to arrive at the other two flavors
to cut down on duplication in the config files. Let's use the new merged
defconfigs mechanism instead to merge the configs on the fly.
