Instead of removing this, since compatible is correct here, I think a
cpus yaml file needs to be added to properly define mips CPU's but
compatible strings using all around the sources are a bit messy. Take
a look of how is this done for arm [0]

I think syscon nodes need to use 'syscon' in the node name, but I am
not 100% sure.
