Queuing this patch for v3.8. Since the config options are removed there
is no use having code which refers to them. The patch has been tested on
DM644x and DM365 in both host and gadget mode (I will add this
information to commit text while committing). Without this patch .mode
seems to be defaulting to MUSB_UNDEFINED which I think is definitely wrong.

Thanks,
Sekhar
