The interrupt-controller property in /chosen just points to the
system's top-level interrupt controller to make it easier for the
kernel to find in the tree.  I think most platforms don't actually
need or use it at present, but booting-without-of does recommend it.

As such it's a property of the board, not something which will change
from boot to boot.  It would therefore be rather strange for the
bootloader to poke this property.
