[PATCH] ALSA: usb-audio: Add capture support for Saffire 6 (USB 1.1)

[Alexander Tsoy]

Capture and playback endpoints on Saffire 6 (USB 1.1) resides on the same
interface. This was not supported by the composite quirk back in the day
when initial support for this device was added, thus only playback was
enabled until now.
