Since this is part of the autoboot functionality, it makes sense to name it with an AUTOBOOT prefix. No mainline boards use it so this should be safe, and downstream boards will need to adjust.
Since this option is just an integer value, it really needs another option to control whether the feature is enabled or not. Add a new CONFIG_USE_AUTOBOOT_MENUKEY for that. This fits better with how things are done with Kconfig, avoiding the need to use a specific value to disable the feature.
