Creates a new MPU-401 instance.
</p><p>
Note that the rawmidi instance is returned on the rrawmidi argument,
not the mpu401 instance itself. To access to the mpu401 instance,
cast from rawmidi->private_data (with struct snd_mpu401 magic-cast).
</p><p>
Returns zero if successful, or a negative error code.
