ALSA: usb-audio: Scarlett Gen 2 mixer interface Add mixer quirk for the Focusrite Scarlett 6i6, 18i8, and 18i20 Gen 2 audio interfaces. Although the interfaces are USB compliant, additional input/output level controls and hardware routing/mixing functionality are available using proprietary USB requests. Signed-off-by: Geoffrey D.

ALSA: usb-audio: scarlett2: Improve driver startup messages Add separate init function to call the existing controls_create function so a custom error can be displayed if initialisation fails. Use info level instead of error for notifications. Display the VID/PID so device_setup is targeted to the right device. Display "enabled" message to easily confirm that the driver is loaded.
