            nouveau_nvkm_subdev_instmem_gk20a.c

Log Message:
nouveau_nvkm_subdev_instmem_gk20a.c: Use BUS_DMA_PREFETCHABLE.

Matches Linux's pgprot_writecombine.

Unclear where the appropriate bus_dmamap_sync happens, or is supposed
to happen -- not using it would be wrong, but asking for a
prefetchable mapping may paper over symptoms, at least!
