Change subject: mb/google/volteer: Configure DP_HPD as PAD_NC and disable DdiPortHpd
......................................................................
Patch Set 4:
Patch Set 2:
Native function pin mux for DPs are done by FSP after pin mux by gpio.c
So, we also need to configure below in overridetree.cb for not confuring DP_HPD1 and DP_HPD2.
register "DdiPort1Hpd" = "0"
register "DdiPort2Hpd" = "0"
Note that these are enabled in devicetree.cb in baseboard.
done.
