dt-bindings: can: renesas,rcar-canfd: Document RZ/T2H and RZ/N2H SoCs

Document the CAN-FD controller used on the RZ/T2H and RZ/N2H SoCs. The
CAN-FD IP is largely compatible with the R-Car Gen4 block, but differs
in that AFLPN and CFTML are different, there is no reset line for the IP,
and it only supports two channels.

Sync the resets and reset-names schema handling with other CAN-FD SoCs so
DT validation stays consistent and maintainable.
