Let me make sure I have this correct.  At this point, we would want it
to be fsl,flexcan here.  If, at some point, we find the i.MX-wonderful
has diverged from the -p1010, we would, at that point in the code, use
of_device_is_compatible to differentiate the two, correct?  That would
mean we should make no change to this patch for the fsl,flexcan-p1010,
right?
