bindings: Update usage of eUSB2 repeater phandle with eUSB2 PHY

Browse Source 
Add usb-repeater with eUSB2 repeater phandle (mandatory) for allowing
eUSB2 PHY driver to call into eUSB2 repeater driver related interfaces
for reset, init and updating its configuration.

Add dummy-supply with eUSB2 repeater phandle (optional) for enforcing
probe ordering between eUSB2 repeater driver and eUSB2 PHY driver.
