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

[ Upstream commit 470757f5b3a46bd85741bb0d8c1fd3f21048a2af ]

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.
