As Jonas Gorske said in his patch:
Disable cpu_has_mmips for everything but SEAD3 and MALTA. Most of
these platforms are from before the micromips introduction, so they
are very unlikely to implement it.
Reduces an -Os compiled, uncompressed kernel image by 8KiB for
BCM63XX.
This patch taks a different approach than his, we gate the runtime
test for microMIPS by the config symbol SYS_SUPPORTS_MICROMIPS.
