Document support for the CAN-FD Controller in the Renesas R-Car
V3H2 (R8A77980A) SoC, which is similar to CAN-FD on R-Car V3H, but
supports a third channel.

As "renesas,r8a77980a-canfd" already uses "renesas,rcar-gen3-canfd" as a
fallback (which lets us use two channels with existing drivers), and the
driver doesn't have special handling for "renesas,r8a77980-canfd", I see
no need to complicate the bindings with "renesas,r8a77980-canfd" as a
second fallback like:
- items:
- const: renesas,r8a77980a-canfd # R-Car V3H2
- const: renesas,r8a77980-canfd # R-Car V3H
- const: renesas,rcar-gen3-canfd # R-Car Gen3 and RZ/G2
