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).
