Improvements to Steinberg UR-44 device support

alsa-project/alsa-ucm-conf pull request #584 was opened from peterix:

- Relabeled the inputs and outputs to make sense considering the device's physical layout and internals - Added one more USB device ID for the UR44 (0x1704 is a non-C variant) - Added stereo inputs in sensible combinations for the various inputs on the device - 1 for inputs 5 & 6 in the back - 3 'adjacent ones' for the 4 inputs in the front - 1 & 2 - 2 & 3 - 3 & 4
