dt-bindings: can: renesas,rcar-canfd: Document RZ/G3E support
Document support for the CAN-FD Interface on the RZ/G3E (R9A09G047) SoC,
which supports up to six channels.
The CAN-FD module on RZ/G3E is very similar to the one on both R-Car V4H
and RZ/G2L, but differs in some hardware parameters:
* No external clock, but instead has ram clock.
* Support up to 6 channels.
* 20 interrupts.
