Subject: ALSA: hda/tas2781: remove digital gain kcontrol

From: Gergo Koteles <soyer@xxxxxx>

commit ae065d0ce9e36ca4efdfb9b96ce3395bd1c19372 upstream.

The "Speaker Digital Gain" kcontrol controls the TAS2781_DVC_LVL (0x1A)
register. Unfortunately the tas2563 does not have DVC_LVL, but has
INT_MASK0 in 0x1A, which has been misused so far.

Since commit c1947ce61ff4 ("ALSA: hda/realtek: tas2781: enable subwoofer
volume control") the volume of the tas2781 amplifiers can be controlled
by the master volume, so this digital gain kcontrol is not needed.

Remove it.
