mainboard/volteer: Update Aux settings for Port 0
On Volteer port 0 (MB PORT) does not have a retimer so the port needs
to be configured for the SOC to handle Aux orientation flipping. This
requires 2 changes setting the TcssAuxOri UPD to 1 for port 0 (Bit 0)
and configuring AUXP and AUXN GPIOs to Native Function 6 so SOC can
control the orientation
BUG=b:145220205
BRANCH=NONE
TEST=booted Volteer proto 2 and verified that the AUX channels flip
when the cable is flipped
