arm64: dts: renesas: rzg2lc-smarc: Disable CAN-FD channel0

On RZ/G2LC SMARC EVK, CAN-FD channel0 is not populated, and currently we
are deleting a wrong and nonexistent node.  Fixing the wrong node would
invoke a dtb warning message, as channel0 is a required property.
Disable CAN-FD channel0 instead of deleting the node.
