2020-09-14mb/google/delbin: Configure DP_HPD as PAD_NC and disable DdiPortHpdRavi Sarawadi
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 and disables DdiPort1Hpd and DdiPort2Hpd. BUG=b:162566436 TEST=Booted to kernel and verified no kernel HPD pins assertion message on Delbin board.

2020-08-24mb/google/volteer/*/gpio.c: add GPP_D16 to early_gpio_tableCaveh Jalali
GPP_D16 is routed to the main power enable pin on several PCIe SD card controllers on SD daughterboards. We should enable the power to these chips as early as possible so they can participate in PCIe enumeration. BUG=b:162722965 TEST=Verified RTS5261 and GL9755 daughterboards enumerate on PCI and can read SD cards.
