ALSA: hda/tas2781: remove digital gain kcontrol

Browse Source 
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 c1947ce61f ("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.

Fixes: 5be27f1e3e ("ALSA: hda/tas2781: Add tas2781 HDA driver")
