Renesas ARM Based SoC Clk Updates for v4.4

Browse source 
* Consider "zb_clk" suitable for power management
 
   This part of a multi-stage effort by Geert Uytterhoeven to add:
 
   "Clock Domain support to the Clock Pulse Generator (CPG) Module Stop
    (MSTP) Clocks driver using the generic PM Domain, to be used on shmobile
    SoCs without device power domains (R-Car Gen1 and Gen2, RZ).  This allows
    to power-manage the module clocks of SoC devices that are part of the
    CPG/MSTP Clock Domain using Runtime PM, or for system suspend/resume,
    similar to SoCs with device power domains (SH-Mobile and R-Mobile)."
