      phy: fsl-imx8-mipi-dphy: Hook into runtime pm · fa1ce8cd

      This allows us to shut down the mipi power domain on the imx8. The
      alternative would be to drop the dphy from the mipi power domain in the
      SOCs device tree and only have the DSI host controller visible there but
      since the PD is mostly about the PHY that would defeat it's purpose.
      
      This allows to shut off the power domain hen blanking the LCD panel:

      domain                          status          slaves
          /device                                             runtime status
