From: Pierre-Louis Bossart <pierre-louis.bossart@linux.intel.com>
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).
