[PATCH] arm64: dts: renesas: ebisu: Add CAN0 support

[Geert Uytterhoeven]

On R-Car E3, Classical CAN0/1 and CAN-FD share the same sets of pins, so
only one of them can be used at the same time.

Add support for using CAN0 instead of CAN-FD channel 0 on Ebisu.
By default, only CAN-FD channel 0 is enabled, as before.

Signed-off-by: Geert Uytterhoeven <geert+renesas at glider.be>
---
Both CAN0 and CAN-FD channel 0 were tested on Ebisu-4D.

To be queued in renesas-devel for v6.17.
