usb: musb: drop unneeded musb_debug trickery
We have a generic way of enabling/disabling different debug messages on a driver called DYNAMIC_PRINTK. Anyone interested in enabling just part of the debug messages, please read the documentation under: Documentation/dynamic-debug-howto.txt for information on how to use that great infrastructure.
