USB: musb: set version of Blackfin version
All current Blackfin parts are using RTL v1.9, but they don't expose the hardware registers to probe this dynamically. So hardcode the version to v1.9 for now. Need to move the local hwvers related defines higher up in the header so that sub-musb headers may utilize them.
