Well that's the first point: the kernel doesn't need this
at all, it can derive this from the rest of the tree easy
enough.

CHRP does this (in an extra-plus nasty way).

Duplicate node? No way. You can be flexible with adding
extra properties, but every node should represent a (pseudo-)
device, and every device in the system should be represented
by exactly one node.
Or you could make the convention that /aliases/interrupt-controller
points to the root interrupt controller, if you really
think you want this.
