Matus Gajdos 4e1462e7cd ALSA: usb-audio: Add native DSD support for Cambridge Audio streamers 
The Cambridge Audio streamer advertises the UAC2 RAW_DATA format on
altsetting 2 of its playback interface, but without the DSD_RAW quirk
flag the driver exposes it only as a SPECIAL format that cannot be
used.

Add QUIRK_FLAG_DSD_RAW for the device (USB ID 22e8:ca10), so the
altsetting is exposed as DSD_U32_BE, enabling native DSD64/128/256
playback.

Tested with: gst-launch-1.0 filesrc location=file.dsf ! \
                            avdemux_dsf ! dsdconvert ! \
                            alsasink device=hw:2,0
