[PATCH 2/9] dt-bindings: phy: samsung,usb3-drd-phy: add optional orientation-switch

[André Draszik]

orientation-switch is the standard declaration to inform the Type-C mux
layer that a remote-endpoint is capable of processing orientation
change messages.

Add as an optional since not all versions of this phy currently support
or even need the orientation-switch.
