[PATCH 0/3 V2] irqchip: gic: Introduce ARM GICv2m MSI(-X) support

[suravee.suthikulpanit]

From: Suravee Suthikulpanit <Suravee.Suthikulpanit@xxxxxxx>

This patch set introduces support for MSI(-X) in GICv2m specification,
which is implemented in some variation of GIC400 (e.g. gic-400+).

This depends on and has been tested with the V7 of "Add support for PCI in AArch64"
(https://lkml.org/lkml/2014/3/14/320).

Changes in V2:
Re-architect the code to:
    * Use irq_chip for gicv2m instead of using the gic_chip (per Marc suggestion).
    * Remove the overwriting of arch_setup_msi_irq and arch_setup_msi_irqs
      (per Marc suggestion).
    * Add devicetree matching for gic-400-plus for v2m stuff instread of
      re-using gic-400 just to be clear.
    * Misc fix/clean up per Mark Rutland and Marc Zyngier comments
