musb: fix warning in include/linux/usb/musb.h

Fix the following build warning by including linux/compat.h:
include/linux/usb/musb.h:110: warning: 'struct device' declared inside parameter list
include/linux/usb/musb.h:110: warning: its scope is only this definition or declaration, which is probably not what you want

 /* The USB role is defined by the connector used on the board, so long as

Applied, thanks!
