soundwire: intel_ace2x: cleanup DOAIS/DODS settings

Use two variables to save the settings, in preparation of a follow-up
change to read values from _DSD properties.

Starting with this patch, the bitfields will be reordered and listed
MSB-first, as shown in the hardware documentation.

Also note that the default for DOAIS is changed from 0x1 (copy-pasted
value?) to 0x3 (hardware default).
