Er.. I think you're missing something.
My point is that the interrupt-controller property in /chosen *should*
be there, but it doesn't make a lot of sense for it to be set by the
bootloader (because it's a fixed property of the board). Therefore it
should be in the dts, therefore the /chosen node needs to be there to
contain it.
