The CAN-FD Controller in the Renesas R-Car V3H2 (R8A77980A) SoC is very
similar to CAN-FD on other R-Car Gen3 SoCs, but supports a third
channel.
Commit e9ffa12e02e19339 ("can: rcar_canfd: Add rnc_field_width variable
to struct rcar_canfd_hw_info") removed the assumption of a maximum of
two channels on controllers using the R-Car Gen3 register layout. Hence
add support for a third channel by increasing the maximum number of
channels on R-Car Gen3 to three.
Just like on R-Car Gen4, the applicable maximum numbers of channels is
enforced by SoC-specific rules in the DT bindings, and the "dtbs_check"
make target.
