phy: rockchip: inno-usb2: Fix improper use of UCLASS_PHY
The Rockchip USB2PHY glue driver improperly present itself as a
UCLASS_PHY driver, without ever implementing the required phy_ops.
This is something that in special circumstances can lead to a NULL
pointer dereference followed by a SError crash.
Change the glue driver to use UCLASS_NOP to fix this.
