ALSA: hda/generic: Unconditionally prefer preferred_dacs pairs

Browse Source 
[ Upstream commit 1c801e7f77445bc56e5e1fec6191fd4503534787 ]

Some time ago, we introduced the obey_preferred_dacs flag for choosing
the DAC/pin pairs specified by the driver instead of parsing the
paths.  This works as expected, per se, but there have been a few
cases where we forgot to set this flag while preferred_dacs table is
already set up.  It ended up with incorrect wiring and made us
wondering why it doesn't work.

Basically, when the preferred_dacs table is provided, it means that
the driver really wants to wire up to follow that.  That is, the
presence of the preferred_dacs table itself is already a "do-it"
flag.

In this patch, we simply replace the evaluation of obey_preferred_dacs
flag with the presence of preferred_dacs table for fixing the
misbehavior.  Another patch to drop of the obsoleted flag will
follow.
