mainboard/google/eve: Enable internal pull-down on USB_C{0,1}_DP_HPD
These lines act as inputs to both EC and AP and when the corresponding
TCPC mux is in low power mode the line is floating. Add an internal
pull-down to each GPIO to prevent it from floating in this state.
BUG=b:35775012
BRANCH=none
TEST=Verify that the kernel does not see a device present on DP when
the TCPC mux is in low power mode.
