Support for EDIROL UM-3ex

Dear all,

This is my naive attempt at adding ALSA device support. The attached patch 
provides support for the EDIROL UM-3ex. This is a 3-port USB midi interface 
with a built-in USB hub and the ability to chain 2 other UM-3x's in a 
master-slave configuration. I only have one, so I do not know how this works 
in practice.

Though this is a 3-port device, I had to throw in that 4th 'Control' interface 
to the definition in order to make the 3rd port work. If I set in/out_cables 
to 0x000b, a 3rd interface appears on the driver, but it does nothing. 
Changing it to 0x000f allows the 3rd interface to work, but of course 
interface 4 does not work because it does not exist.

 - Brent
