Subject: [PATCH v2 0/3] Introduce EC-based watchdog

Chromeos devices are equipped with the embedded controller (EC)
that can be used as a watchdog. The following patches
updates the structures and definitions required to
communicate with EC-based watchdog and implements the
driver itself.

The first version of this patch was sent here:
https://patchwork.kernel.org/project/linux-watchdog/patch/20240117102450.4080839-1-lma@chromium.org/

Changelog
V1->V2:
* Splitted into three patches
* Supplement the watchdog configuration with min/max timeouts
* Removed struct cros_ec_wdt_data  and get aligned to watchdog framework
* Simplified suspend/resume callbacks
* Removed excessive log messages
* Reworked cros_ec_wdt_send_hang_detect() function to be more generic
* Usage of devm_* allowed to delete .remove module callback
* Changed MODULE_ALIAS to MODULE_DEVICE_TABLE
* Moved clearing bootstatus (on EC) to probe() and thanks to that
  got rid of .shutdown() module callback
* Fixed/removed comments, removed unused includes and general cleanup

Best regards,
Lukasz
