arm64: dts: renesas: r8a77965: Add CAN{0,1} placeholder nodes

Browse source

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 308b7e4ba6 ("arm64: dts: r8a7795: Add CAN support")
 - v4.11 commit 909c162524 ("arm64: dts: r8a7796: Add CAN support")
 - v4.12 commit bec0948e81 ("arm64: dts: r8a7796: Add reset control properties")
