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.
