tgl boards: Configure retimer Aux orientation

In order to create a working baseline all ports are being set to have
retimers. Setting the TcssAuxOri UPD to 0 in order for the SoC to not
misconfigure the ports. Volteer will need some additional changes after
this is implemented to account for ports that do not have a retimer.

This setting is in the process of being documented in the TGL EDS and we
can update once it is fully understood what this setting is changing on
the SOC side.

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.
