Add the missing CAN devices node including their pin muxing and clocks.

I could actually only test CAN1 due to the hardware I had available. Also
CAN0 conflicts with DBGU pins, which I had to use.

I would stop adding that comment as this is pretty clear that your are
setting PA9 and P10 to periph B. A more useful kind of comment is what
pin it conflicts with. Maybe something like:
<AT91_PIOA 9 AT91_PERIPH_B AT91_PINCTRL_NONE /* CANRX0, conflicts with DRXD */

Last nitpick, could you make that be CANRX0 and CANTX0 ?

And CANRX1, CANTX1 here so that it is the same as the datasheet.
Then you can add my acked-by.
