v2:
- Add vendor-prefix to DT binding definition header file.
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.
