reboot-mode: add support for reboot mode control
A new driver uclass is created to handle the reboot mode control.
The new uclass driver is updating an environment variable with the
configured reboot mode. The mode is extracted from a map provided
at initialization time. The map contains a list of modes
and associated ids.
