[Impact]
The rear lineout jack can't work. If users plug a headphone or audio
cable into the lineout jack, nothing happens, the audio still output
from internal speaker. The expected behaviour is the lineout is
active and the sound is routed to lineout jack from internal speaker.

[Fix]
apply the ALC274_FIXUP_DELL_AIO_LINEOUT_VERB, this will set the
lineout pin to be a correct configuration value.


[Test Case]
plug headphone into the rear lineout jack, system can detect lineout
jack is plugged and the audio output is routed to lineout jack from
internal speaker.


[Regression Potential]
Very low, this patch is specific to one Dell machine model.
