[PATCH] USB: Gadget library: centralize gadget controller numbers

Browse Source 
This patch centralizes the assignment of bcdDevice numbers for different
gadget controllers.  This won't improve the object code at all, but it
does save a lot of repetitive and error-prone source code ... and will
simplify the work of supporting a new controller driver, since most new
gadget drivers will no longer need patches (unless some hardware quirks
limit USB protocol messaging).

Added minor cleanups and identifer hooks for the UDC in the Freescale
iMX series processors.
