I think Arnd is right. In this case it should be "nuvoton,npcm750-smp". We can
use CPU_METHOD_OF_DECLARE to alias to as many compatible properties as needed.

Although everything in the 7xx family currently is either single core or has the
same SMP behavior, you could paint yourself into a corner if you were to make
one SMP device in the 7xx family which behaves differently from all other
devices and then need to come up with new compatible string names just for that.
