chromeos: Clean up elog handling

Browse Source 
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.
