this.

Commit 244829226f47ffb4 ("[media] timberdale: do not select TIMB_DMA")
dropped the dependency of VIDEO_TIMBERDALE on DMADEVICES, and thus the
implicit dependency on HAS_DMA. VIDEO_TIMBERDALE selects
VIDEOBUF_DMA_CONTIG, which bypasses its dependency on HAS_DMA. Make
VIDEO_TIMBERDALE depend on HAS_DMA to fix this.
