ALSA: usb-audio: Add custom mixer status quirks for RME CC devices
Adds several vendor specific mixer quirks for RME's Class Compliant USB devices. These provide extra status information from the device otherwise not available. These include AES/SPDIF rate and status information, current system sampling rate and measured frequency. This information is especially useful in cases where device's clock is slaved to external clock source. Signed-off-by: Jussi Laako <jussi@sonarnerd.net> Signed-off-by: Takashi Iwai <tiwai@suse.de>
