There is still the gpio support patch pending, which I have to review
and test.

After this has been merged, we can have a look at this patch.

It might actually not be needed anymore, as we can describe a CAN
transceiver switched by a GPIO in the DT. Hopefully we don't run into
some crazy circular dependencies or similar issues.

Marc
