ALSA: usb - Quirk to disable master volume control in PCM2702

Disable the master volume control in the PCM2702 chipset.

The datasheet documents two independent channel volume controls, one
master mute control and one master volume control. All controls are
fully functional except for the master volume control, which returns
USB stalls on all GET requests.
