Add documentation to describe usage of the new fixed transceiver binding.
This new binding is applicable for any CAN device therefore it exists as
its own document.

+Fixed transceiver Device Tree binding
+------------------------------
+
+CAN transceiver typically limits the max speed in standard CAN and CAN FD
+modes. Typically these limitations are static and the transceivers themselves
+provide no way to detect this limitation at runtime. For this situation,
+the "fixed-transceiver" node can be used.
+
+Required Properties:
+ max-bitrate: a positive non 0 value that determines the max
+ speed that CAN/CAN-FD can run. Any other value
+ will be ignored.
+
+Examples:
+
+Based on Texas Instrument's TCAN1042HGV CAN Transceiver
+
+m_can0 {
+ ....
+ fixed-transceiver@0 {
+ max-bitrate = <5000000>;
+ };
+ ...
+};
