huh.. I think we can have a much simpler fix. All this binding in board file
was introduced to support platforms that has multiple PHYs of the same type.
But musb/omap2430.c serves platforms that has only one PHY of a particular
type. We can just go back to usb_get_phy(enum usb_phy_type type) instead of
'usb_get_phy_dev' in omap2430.c. Felipe, what do you think?

Cheers
