ALSA: mpu401_uart: Use standard print API

Browse Source 
Use the standard print API with dev_*() instead of the old house-baked
one.  It gives better information and allows dynamically control of
debug prints.

The assignment of mpu->rmidi was moved to an earlier place, so that
dev_*() can access to the proper device pointer.
