Renesas ARM Based SoC Drivers Updates for v4.15

Browse Source 
Add basic support for R-Car V3M (R8A77970) SoC.
 
 Sergei Shtylyov says:
 
 * Add support for R-Car V3M (R8A77970) SoC power areas to the R-Car SYSC
   driver
 
 * Add support for identifying the R-Car V3M (R8A77970) SoC
 
 * Add support for R-Car V3M (R8A77970) to the R-Car RST driver -- this
   driver is  needed  for the clock driver to work
