additional data for reboot modes that accept two arguments.

+ This driver gets reboot mode arguments and calls the write
+ interface to store the magic and an optional cookie value
+ in special register or ram. Then the bootloader can read it
+ and take different action according to the argument stored.
All mode properties are vendor specific, it is a indication to tell
the bootloader what to do when the system reboots, and should be named
- as mode-xxx = <magic> (xxx is mode name, magic should be a non-zero value).
+ as mode-xxx = <magic cookie> (xxx is mode name, magic should be a
+ non-zero value, cookie is optional).
For example, modes common Android platform are:
- normal: Normal reboot mode, system reboot with command "reboot".
