ALSA: usb-audio: Support string-descriptor-based quirk table entry

Browse source

Some quirky devices do not have a unique VID/PID. Matching them using
DEVICE_FLG() or VENDOR_FLG() may result in conflicts.

Add two new macros DEVICE_STRING_FLG() and VENDOR_STRING_FLG() to match
USB string descriptors (manufacturer and/or product) in addition to VID
and/or PID, so that we can deconflict these devices safely.

No functional change intended.
