This can be static?

Is it possible to also reserve the resources for these registers at
this point in the boot sequence?

Is there a strong reason to change the compatible string? Looks to me
like either the new driver or the old driver will bind depending on
what is in the machine description. No need for a new string?

Shouldn't this use the new IRQCHIP_DECLARE mechanism?

.. which lets this go away, use the generic irqchip_init instead of
orion_init_irq.
