This patch adds support for R-Car M3-W. This patch also adds R-Car
Gen3 generic version's compatible and changes ".compatible" in
the usb3_of_match from "renesas,r8a7796-usb3-peri" to
"renesas,rcar-gen3-usb3-peri".

- compatible: Must contain one of the following:
- "renesas,r8a7795-usb3-peri"
+ - "renesas,r8a7796-usb3-peri"
