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

v1->v2:
 * Updated the commit header and description.
 * Fixed the bot warning by disabling the channel instead of deleting it.
