If NO_DMA=y:

    ERROR: "bad_dma_ops" [drivers/iio/adc/ti_am335x_adc.ko] undefined!

Add a dependency on HAS_DMA to fix this.

Applied to the fixes-togreg-post-rc1 branch of iio.git (will unwind
this fun branch shortly now we are post rc1) and marked for stable
with an appropriate fixes tag added.

Thanks,
