Even though the Generic PHY framework is the more preferable way of setting the USB PHY up, there are still many dts-files and DT bindings which rely on having the legacy "usb-phy" specified to attach particular USB PHYs to USB cores. Let's have the "usb-phy" property described in the generic USB HCD binding file so it would be validated against the nodes in which it's specified. Mark the property as deprecated to discourage the developers from using it.
