mb/google/rex: Set AUX orientation at SoC to follow cable for kb8010

This configures the SoC to flip the orientation of the AUX pins to
follow the orientation of the cable when using the kb8010 retimer. This
is necessary when there is no external retimer/mux or the retimer/mux
does not implement the flip. The kb8010 retimer does not support this
feature, so let the SoC do the flip.

BUG=b:267589112
TEST=verified DP-ALT mode works in both cable orientations on rex with
	reworked kb8010 DB by flykt@
