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.

Please add entries for the other interfaces. Without them, interface zero will not be attached, and the other interface are not handled atomically.
And in theory, the device entries are supposed to be sorted by ID.
