Subject: [PATCH 2/2] dt-bindings: can: renesas,rcar-canfd: Make interrupt-names required

The Renesas R-Car CAN FD Controller always uses two or more interrupts.
Make the interrupt-names properties a required property, to make it
easier to identify the individual interrupts.

Update the example accordingly.
