mb/google/octopus: Fix termination for unused dual voltage pins
These pins should not have pull downs configured in standby state as that
can cause contention on the termination circuitry and lead to incorrect
behavior as per Doc# 572688 Gemini Lake Processor GPIOTermination
Configuration.
BUG=b:79982669
TEST=Checked that code compiles with changes.
