Commit 98898f3bc83c8 ("phy: rockchip-inno-usb2: support otg-port for
rk3399") introduces two new properties. The extcon property is used to
detect the cable-state, and the rockchip,utmi-avalid is used to indicate
which register should be used to detect the vbus state.
Document these properties in the documentation binding.
Fixes: 98898f3bc83c8 ("phy: rockchip-inno-usb2: support otg-port for rk3399")
