arm64: dts: ti: k3-j7200-som-p0: Add support for CAN instance 0 in main domain

Browse Source 
CAN instance 0 in the main domain is brought on the J7200 SoM through
header J1. Thus, Add transceiver dt node to add support for this CAN
instance.

Also, add the mux dt nodes to route CAN High and Low lines coming
from the SoC to the Common Processor Board.
