2021-01-16mb/google/volteer: do UART pad config at board-levelMichael Niewöhner
UART pad configuration should not be done in common code, because that may cause short circuits, when the user sets a wrong UART index. Thus, add the corresponding pads to the early UART gpio table for the board as a first step. Common UART pad config code then gets dropped in CB:48829. Also switch to `bootblock_mainboard_early_init` to configure the pads in early bootblock before console initialization, to make the console work as early as possible. The board does not do any other gpio configuration in bootblock, so this should not influence behaviour in a negative way (e.g. breaking overrides).

2021-01-11mb/google/volteer: Set FORCE_PWR low at boot timeJohn Zhao
While FORCE_PWR is set high, it prevents retimer from entering low power state. S0ix failure occurs while USB4 Gatkex is connected on Port-0. This change sets FORCE_PWR(GPP_H10) low. This FORCE_PWR GPIO will be toggled by kernel through DSM method while updating retimer firmware. BUG=b:174166586 Cq-Depend: chromium:2594438 TEST=Verifed s0ix cycles with USB4 Gatkex connected on Port-0.

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.
