From: Cliff Cai <cliff.cai@xxxxxxxxxx>
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.

v2
- declare a proper 1.9 hwvers define and use that
- have to move the defines up before musb_regs.h include :/
