Second Round of Renesas ARM Based SoC Updates for v4.16

* rcar-sysc: Keep wakeup sources active during system suspend

  Geert Uytterhoeven says "If an R-Car SYSC slave device is part of the
  CPG/MSTP or CPG/MSSR Clock Domain and to be used as a wakeup source, it
  must be kept active during system suspend.

  Currently this is handled in device-specific drivers by explicitly
  increasing the use count of the module clock when the device is
  configured as a wakeup source.  However, the proper way to prevent the
  device from being stopped is to inform this requirement to the genpd
  core, by setting the GENPD_FLAG_ACTIVE_WAKEUP flag.

  Note that this will only affect devices configured as wakeup sources."
