how about moving usb_bind_phy() calls to omap2430.c ?

The only problem is if some board comes with a PHY other than
twl4030_usb, but in that case we can add a separate compatible flag and
treat it properly. We only need to bind the phy in non-DT case anyway,
so that's temporary. It might be better than to reintroduce the IDR in
musb_core.c.
