soc/intel/tigerlake: Configure IOM_TYPEC_SW_CONFIGURATION_3
FSP UPD TcssAuxOri is used for setting the IOM_TYPEC_SW_CONFIGURATION_3. Configure TcssAuxOri to retimer enabled on the port 2 Type-C port. This setting informs the SoC that a retimer is taking care of SBU orientation therefore it does not need to do any flipping. The IOM_TYPEC_SW_CONFIGURATION_3 is a bitfield that controls the aux orientation settings for the Type-C ports. The TGL EDS describes this setting and what each bit represents. Reference section 3.6.5 in TGL EDS #575681 BUG=b:145943811 BRANCH=none TEST=Boot to OS and check Type-C port1 Display on volteer, Connecting Type-C display should work regardless of Type-C cable orientation.
