In order to support the physical recovery GPIO on sarien it needs
to enable the option VBOOT_PHYSICAL_REC_SWITCH and set the GPIO
number in the coreboot table appropriately so that depthcharge can
correctly determine the GPIO number. The same is done for the
write protect GPIO in this table.
Additionally since we are reading a recovery request from H1 it
needs to cache the result since H1 will only return true on the
first request. All subsequent queries to H1 will not indicate
recovery. Add a CAR global here to keep track of the state and
only read it from H1 the first time.

On the Sarien/Arcada platforms, the EC is not trusted to provide
the state of the ESC+REFRESH+PWR recovery combination. On these
platforms the Cr50 latches the state of REFRESH+PWR for use as the
recovery mode key combination.

Sarien is a new board using Intel Whiskey Lake SOC. It also uses
the newly added Wilco EC, enabled in a separate commit.
Sarien is not a true reference board, it is just one variant of
a very similar design. For that reason it is not considered the
baseboard but rather a standalone variant.
