mvebu driver irqchip for v3.10

 - move the armada irqchip driver to drivers/irqchip/

Note:
 - I asked tglx if it was ok to take this series on 10 Apr due to it's complex
   dependencies.  5+ days have passed with no objection.
 - I put this driver in a separate mvebu branch in case tglx or others object,
   it can be dropped with minimal impact to other work.
irqchip: armada-370-xp: slightly cleanup irq controller driver

In preparation for the introduction of MSI support in the IRQ
controller driver, we clarify the implementation of IPI using
additional defines for the manipulation of doorbells. Just like IPIs
are implemented using doorbells, MSIs will also use doorbells, so it
makes sense to do this preparatory cleanup first.
