  This driver gets the reboot mode magic value from the reboot-mode driver
  and stores it in the NVMEM cell named "reboot-mode". The bootloader can
  then read it and take different action according to the value.

      A phandle pointing to the nvmem-cells node where the vendor-specific
      magic value representing the reboot mode is stored.
