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

+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.
+
+Properties:
+
+Optional:
+ max-arbitration-speed: a positive value non 0 value that determines the max

   Too many values. :-)

+			 speed CAN can run in non CAN-FD mode or during the
+			 arbitration phase in CAN-FD mode.
+
+ max-data-speed:	 a positive value that determines the max data rate
+			 that can be used in CAN-FD mode. A value of 0
+			 implies CAN-FD is not supported by the transceiver.
