usb: fix building musb drivers
Commit 3dacdf11 "usb: factor out state_string() on otg drivers"
broke building musb drivers since there is already another
otg_state_string() function in musb drivers, but with different
prototype. Fix musb drivers to use common otg_state_string(), too.
Also provide a nop for otg_state_string() if CONFIG_USB_OTG_UTILS
is not defined.
