Staging: most: MOST and MOSTCORE should depend on HAS_DMA

If NO_DMA=y:

    ERROR: "dma_free_coherent" [drivers/staging/most/mostcore/mostcore.ko] undefined!
    ERROR: "dma_alloc_coherent" [drivers/staging/most/mostcore/mostcore.ko] undefined!

As all MOST sub drivers use DMA functionality, add a dependency on
HAS_DMA to MOSTCORE, and to MOST, which selects MOSTCORE.
