[RFC PATCH 2/6] ARM: OMAP: USB: Add phy binding information

This is in preparation for 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 for OMAP platforms here.

This kind-of binding should be done in all the platforms (I've done only
for OMAP platform).
