ALSA: usb-audio: Add support for Akai MPC Element USB MIDI controller

Browse Source 
The Akai MPC Element incorrectly reports its bInterfaceClass as 255, but
otherwise implements the USB MIDI spec correctly.

This adds a quirks-table.h entry which allows the device to be
recognized as a standard USB MIDI device.
