The R-Car SYSC PM Domain driver has to power manage devices in power areas using clocks. To reuse code and to share knowledge of clocks suitable for power management, this is ideally done through the existing cpg_mssr_attach_dev() and cpg_mssr_detach_dev() callbacks. Hence these callbacks can no longer rely on their "domain" parameter pointing to the CPG/MSSR Clock Domain. To handle this, keep a pointer to the clock domain in a static variable. cpg_mssr_attach_dev() has to support probe deferral, as the R-Car SYSC PM Domain may be initialized, and devices may be added to it, before the CPG/MSSR Clock Domain is initialized. Dummy callbacks are provided for the case where CPG/MSTP support is not included, so the rcar-sysc driver won't have to care about this.
