Kishon Vijay Abraham I 51482be9dc ARM: OMAP: USB: Add phy binding information 
This is w.r.t the changes in PHY library to support adding and getting
multiple PHYs of the same type. In the new design, the
binding information between the PHY and the USB controller should be
specified in the platform specific initialization code. So it's been
done here for OMAP platforms.
