Skip the unused DAIO type per model (SPDIFIO on CTSB073X, SPDIFI_BAY
on all others) and use the matching DAIO type directly as da_desc
type. This removes the mismatch 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().

It's error-prone to use ternary operators as open code in many places.
Better to define a function instead.

... and this is even reversed value assignment which is rather
confusing.  Rather write with a simple if/else, such as:

		 if ((i == SPDFIO && atc->model == CTSB073X) ||
		     (i == SPDIFI_BAY && atc->model != CTSB073X))
			continue;

Avoid unnecessary spacing changes.  The previous code is fine about
indentation.
