[PATCH v4 1/2] dt-bindings: usb: nxp,ptn5110: add optional orientation-gpios property

[Xu Yang]

The Type-C chip know the cable orientation and then normally will set the
switch channel to correctly configure the data path. Some chips itself
support to output the control signal by indicating the capability in
bit[0] of STANDARD_OUTPUT_CAPABILITIES register and do it in
CONFIG_STANDARD_OUTPUT register. For PTN5110 which doesn't present this
capability currently there is no way to achieve the orientation setting.
Add an optional "orientation-gpios" property to achieve the same purpose.
