ALSA: hda/generic: Add option to enforce preferred_dacs pairs
The generic parser accepts the preferred_dacs[] pairs as a hint for
assigning a DAC to each pin, but this hint doesn't work always
effectively. Currently it's merely a secondary choice after the trial
with the path index failed. This made sometimes it difficult to
assign DACs without mimicking the connection list and/or the badness
table.
This patch adds a new flag, obey_preferred_dacs, that changes the
behavior of the parser. As its name stands, the parser obeys the
given preferred_dacs[] pairs by skipping the path index matching and
giving a high penalty if no DAC is assigned by the pairs. This mode
will help for assigning the fixed DACs forcibly from the codec
driver.
