[PATCH v2] ALSA: usb-audio: Add SPDX id to midi.c

[Tim Bird <tim.bird@sony.com>]

Add an SPDX-License-Identifier line to sound/usb/midi.c
Use 'BSD-Source-Code' as part of the OR for the
license id.

This patch depends on the one for opl4 sound driver, as that
one adds the BSD-Source-Code license for the LICENSES directory.

V1 -> V2
 - Change to use BSD-Source-Code, from the weird LicenseRef variant
   thing I was doing before.  This is a supported SPDX ID.
 - Use better subject prefix (ALSA: usb-audio:)
