Support identifying usb midi device using usb sysfs Out-of-tree ACK patches previously enabled MIDI device identification via the "/sys/class/android_usb/android0/f_midi/alsa" sysfs node. This change introduces a new, upstream-compliant method for MIDI device identification. This method requires the upstream patch [1] within the underlying ACK.
