Maybe convert all the WARN/INFO/ERR uses to dev_<level> equivalents too?
Use more typical logging styles:
o Add musb_<level> macros that use dev_<level>
o Add struct musb * to musb_<level> calls
o Remove __func__ and __LINE__ uses
o Remove newlines from formats and add to macros for consistency with musb_dbg
o Remove unnecessary newlines from musb_dbg uses
o Coalesce formats and align arguments
