Introduce a LIN (local interconnect network) abstraction on top of CAN.
This is a glue driver adapting CAN on one side while offering LIN
abstraction on the other side. So that upcoming LIN device drivers can
make use of it.

Hi Christoph,

Sparse flags that the structures defined by the above code are not
declared elsewhere, and therefore likely should be static.
