mb/google/brya/var/nereid: Enable AUX DC biasing on C0 and C1

C0 has no redriver, so enable SBU muxing in the SoC.

C1 has a redriver which does SBU muxing, so disable SBU muxing in the
SoC. However, this also disables AUX biasing when the pins are
configured as NF6. So instead configure the C1 AUX bias pins as GPO.

BUG=b:227259673
TEST=Voltages are correct on the C0 and C1 AUX bias pins
