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.
