Clemens Ladisch f009ad9b39 [ALSA] oxygen: change model-specific PCM device configuration 
When specifying which PCM devices to use, model drivers now use flags
that also specify the routing between PCM devices and DMA channels
instead of just DMA channel bits.  This simplifies some code that checks
for these flags.
