CAN instance 0 in the mcu domain is brought on the j721e-sk board through header J1. Thus, add its respective transceiver 1 dt node to add support for this CAN instance. CAN instances 0, 5 and 9 in the main domain are brought on the j721e-sk board through headers J5, J6 and J2 respectively. Thus, add their respective transceivers 2, 3 and 4 dt nodes to add support for these CAN instances.
