USB-Audio: Add Audient EVO4

This is a 4in/4out device with 1 analog stereo out and 2 analog mono in.
The hardware mixed loopback interface takes up the remaining 4 channels.
Without this UCM the device is configured as 4.0 surround for in and out.
I copied the Windows config except for the stereo mic mix.

Modifying hardware volumes/gain other than main output seems to require
a driver or external software similar to the one found on github at the
repo github.com/vijay-prema/audient-evo-linux-tools

Closes: #303
