[PATCH v8 25/29] phy: rockchip: usbdp: Clear USB status on PHY exit

[Sebastian Reichel]

Ensure the USB status flag is cleared when the USB3 PHY is
exited while the system is in DP-only mode. This can happen
if the USB3 controller device is unbound while a DP-only
adapter is plugged into the USB-C port.
