mb/google/volteer: Configure GPP_A19 and GPP_A20 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.
DP_HPD had been removed for EVT design as those events are through eSPI.
This change configures GPP_A19 and GPP_A20 to be no connection.

BUG=b:162566436
TEST=Booted to kernel and verified no kernel HPD pins assertion message
on Volteer EVT board.
