mb/google/volteer/variants/eldrid: Configure DP_HPD as PAD_NC
GPP_A19(DP_HPD1) and GPP_A20(DP_HPD2) were configured native function
(NF1) without internal pull-down which wrongly presents HPD interrupts.
This change configures GPP_A19 and GPP_A20 to be no connection and
disables DdiPort1Hpd and DdiPort2Hpd.
