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.
