dt-bindings: phy: rockchip-inno-usb2: add properties for pipe sel

The rk3588 usb otg0/1 controllers depend on the pipe
phystatus which from usb3 phy by default. When the usb3
phy is disabled, it needs to select the pipe phystatus
from usb grf. This patches add new properties to select
pipe phystatus if needed.
