[PATCH] ALSA: usb-audio: Add quirk flags for Behringer UV1

[Nick Pegg]

The Behringer UV1 is a microphone audio processor with a USB audio
interface, which experiences periodic stutters unless implicit_fb is used.

This seems to be a similar device to the Behringer UMC series, so I
copied the quirks from those. I've confirmed that my own UV1 works great
with these flags set.
