     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.
