ULPI bus binding

Phys that are behind a ULPI connection can be described with the following
binding. The host controller shall have a “ulpi” named node as a child, and
that node shall have one enabled node underneath it representing the ulpi
device on the bus.

EXAMPLE

usb {
compatible = “vendor,usb-controller”;

ulpi {
    phy {
        compatible = "vendor,phy";
    };
};

};
