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.
