ALSA: usb-audio: Add MIDI support for Steinberg MI2/MI4
commit 0689a86ae814f39af94a9736a0a5426dd82eb107 upstream.
The Steinberg MI2 and MI4 interfaces are compatible with the USB class
audio spec, but the MIDI part of the devices is reported as a vendor
specific interface.
This patch adds entries to quirks-table.h to recognize the MIDI
endpoints. Audio functionality was already working and is unaffected by
this change.
