[PATCH v2 0/3] Update cros-ec-spi for fingerprint devices

[Stephen Boyd <swboyd@chromium.org>]

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 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

  platform/chrome: cros_ec_spi: Match cros-ec-fp compatible
