Transmit and receive cpu slot masks of each TDM lane
When omitted, mask is assumed to have to no slots. A valid
interface must have at least one slot, so at least one these
mask should be provided with an enabled slot.

description:
dai-link representing backend links should have at least one subnode.
One subnode for each codec of the dai-link. dai-link representing
frontend links have no codec, therefore have no subnodes
