I think these properties weren't specified in the OF CHRP ISA PIC device
binding document for the PIC node, thus I may have forgotten about them
(CHRP also defines a parent interrupt controller for the PIC, right?).
But the AmigaOne is not a CHRP platform, so I'll add them to the device
tree and then I will see how it works.

Thanks!
