1. Currenty, boot reason is being added to elog only for some ARM32/ARM64 platforms. Change this so that boot reason is logged by default in elog for all devices which have CHROMEOS selected. 2. Add a new option to select ELOG_WATCHDOG_RESET for the devices that want to add details about watchdog reset in elog. This requires a special region WATCHDOG to be present in the memlayout. 3. Remove calls to elog add boot reason and watchdog reset from mainboards.
