irqchip/gic-v3: Expose GICD_TYPER in the rdist structure
Instead of exposing the GIC distributor IntID field in the rdist structure that is passed to the ITS, let's replace it with a copy of the whole GICD_TYPER register. We are going to need some of this information at a later time. No functionnal change. Signed-off-by: Marc Zyngier <marc.zyngier@arm.com>
