Describe GPIO[0-6] controllers in the R8A7794 device tree.
Based on original patch by Hisashi Nakamura <hisashi.nakamura.ak@xxxxxxxxxxx>.
Signed-off-by: Sergei Shtylyov <sergei.shtylyov@xxxxxxxxxxxxxxxxxx>
Acked-by: Geert Uytterhoeven <geert+renesas@xxxxxxxxx>

Changes in version 3:
- added "power-domains" property to the GPIO device nodes.
Changes in version 2:
- fixed "gpio-ranges" property's last value for GPIO1/5/6;
- added Geert's ACK.
