    description:
      The "loongson,suspend-address" is a deep sleep state (Suspend To
      RAM) firmware entry address which was jumped from kernel and it's
      value was dependent on specific platform firmware code. In
      addition, the PM need according to it to indicate that current
      SoC whether support Suspend To RAM.
