USB-Audio: Add FiiO K11 config

alsa-project/alsa-ucm-conf pull request #360 was edited from ZVNexus:

Without an ALSA config the device shows up as "Digital" and "Analog", and the Analog option has no volume control. The DAC only exposes the headphone jack in USB DAC mode, so just headphones.

Attached some information about the DAC
