[PATCH] Powerpc move of_irq_to_resource from prom.h to prom_parse.c

Powerpc move of_irq_to_resource from prom.h to prom_parse.c

Sorry for the lack of information, it got cut in the previous messages.
Let's start all over again :

In the powerpc architecture, of_irq_to_resource, currently sitting in
prom.h, needs irq_of_parse_and_map and NO_IRQ from asm-powerpc/irq.h.
The solution suggested by Benjamin Herrenschmidt is to move it to
arch/powerpc/kernel/prom_parse.c.

It applies on 2.6.20.
