Changes compared to the BSP:
  - Move from drivers/soc/renesas/ to drivers/pmdomain/renesas/,
  - Include rcar-gen4-sysc glue from "soc: renesas: rcar-gen4-sysc:
    Introduce R-Car Gen4 SYSC driver",
  - Remove unneeded includes,
  - Align second column,
  - Fix names of "a33dga" and "a23dgb" domains,
  - Add missing "a3cr[012]" domains.
