Skip the unused DAIO type per model (SPDIFIO on CTSB073X, SPDIFI_BAY
on all others) and use the correct DAIO type directly as da_desc
type. This removes the mismatch and misleading between the actual
DAIO resource and the da_desc type like SPDIFI_BAY (formerly SPDIFI1).
Update related functions accordingly, and drop the unreachable
SPDIFI_BAY case from the hw20k2 daio_device_index().
