This patch series introduces a DT binding for chromeos fingerprint
devices and then implements support to boot those processors during
driver probe if the BIOS hasn't done it already.

Changes from v3 (https://lore.kernel.org/r/20220318015451.2869388-1-swboyd@chromium.org):
 * Drop spi_device_id because it isn't used
 * Dropped struct members for gpios
 * Picked up tags

Changes from v2 (https://lore.kernel.org/r/20220317005814.2496302-1-swboyd@chromium.org):
 * Dropped cros-ec spi dt properties that aren't of use right now
 * Picked up tags

Changes from v1 (https://lore.kernel.org/r/20220314232214.4183078-1-swboyd@chromium.org):
 * Properly do the boot sequence
 * Add a message that we're booting and delaying a while
 * Fix typo in commit text
 * Change binding to not spell out reset-gpios and indicate that boot0
   is about asserting boot mode
 * Split device id to different patch as it's a different topic from
   booting
