That doesn't matter. We want the code to be as common as possible.
The actual virtual IRQ value is irrelevant. The OF code gives you a
virq number, and you just use that. Any code or board design that
depends on any relationship between the virq and the hwirq is broken.

This is a bad idea. You will just break something else.
