   13   This is a generic poweroff driver using syscon to map the poweroff register.
   14   The poweroff is generally performed with a write to the poweroff register
   15   defined by the register map pointed by syscon reference plus the offset
   16   with the value and mask defined in the poweroff node.
   17   Default will be little endian mode, 32 bit access only.
