Update the reboot-mode binding to support an optional cookie
value in mode-<cmd> properties. The cookie is used to supply
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".
