From: Sam Day <[email protected]> Until now, the reboot-mode uclass didn't wire up a producer path to allow arbitrary changes to the reboot mode. The current impl only uses reboot_mode_ops->set to clear the reboot mode once it has been read at boot-time.
The public API is expanded with a dm_reboot_mode_activate method, which will instruct the given device to activate a particular reboot mode. The first producer, `fastboot reboot`, will be introduced in the next commit.
