interrupt-controller in /chosen is obsolete. Drop it.

32-bit was never a specified property. Drop.

Any node with children must have #address-cells and #size-cells
properties. This one almost certainly needs 'ranges' too. If it has
any bridge control registers, it should have 'reg' also.

It would be kind of neat if you could get this to generate labels and
references, rather than explicit phandles for the interrupt tree.

Ok, I don't really understand why the memory node is duplicated here.
It seems to be covering the same range as the top-level /memory node.

Possibly this should be current-speed, in analogy with ns16550
devices.
