MIPS: use generic dma noncoherent ops for simple noncoherent platforms

Browse Source 
Convert everything not overriding dma-coherence.h to the generic
noncoherent ops.  The new dma-noncoherent.c file duplicates a lot of
the code in dma-default.c, but that file will be gone by the end of
this series.
