[PATCH v2 2/6] dt-bindings: phy-rockchip-typec: move extcon property to be optional.

[Enric Balletbo i Serra]

The extcon property is used to detect the cable-state but some boards
just connect the type-c phy to a regular USB-A connector without any
power-delivery and thus no controller reporting the cable-state.
So the extcon property is not really a required property, move it to be
optional instead.
