irq_to_pending is also a VGIC function. Can you move it to vgic.h?

On V3, I told you that these 2 names are too generic too be exported
here. Please add vgic_* before, so developer won't use them any where...

Please add the relevant maintainers when you add code in other part than
ARM. This time, I've cced them.

I think this code movement should be in another patch and justify why
this function should go in common code.
