dt-bindings: phy-rockchip-typec: deprecate some register properties.

Browse source 
As now the following register properties are in the driver, document as
deprecated these properties and recommend to not use them on new bindings.

The deprecated properties are:

- rockchip,typec-conn-dir : the register of type-c connector direction
- rockchip,usb3tousb2-en : the register of type-c force usb3 to usb2
                           enable control.
- rockchip,external-psm : the register of type-c phy external psm clock
                          selection.
- rockchip,pipe-status : the register of type-c phy pipe status.
