arm64: dts: renesas: r8a77965: Add CAN{0,1} placeholder nodes
According to R-Car Gen3 HW manual rev1.00, R-Car M3-N has two CAN
interfaces, similar to H3, M3-W and other SoCs from the same family.
Add CAN placeholder nodes to avoid below DTC errors:
Error: arch/arm64/boot/dts/renesas/ulcb-kf.dtsi:19.1-6 Label or path can0 not found
Error: arch/arm64/boot/dts/renesas/ulcb-kf.dtsi:25.1-6 Label or path can1 not found
These errors occur *after* the addition of r8a77965-m3nulcb-kf.dts.
Fix them beforehand.
CAN support is inspired from below commits:
- v4.7 commit 308b7e4ba62e ("arm64: dts: r8a7795: Add CAN support")
- v4.11 commit 909c16252415 ("arm64: dts: r8a7796: Add CAN support")
- v4.12 commit bec0948e810f ("arm64: dts: r8a7796: Add reset control properties")
