mb/google/brya/variants/gimble: add TcssAuxOri
Gimble don't have retimer on port0, the port need to be configured for the SOC to handle Aux orientation flipping. Also add "typec_aux_bias_pads" lets the SoC IOM firmware control the Aux DC bias voltages. BUG=b:195087071 BRANCH=none TEST=check both orientation can output display on type-c monitor.
