[PATCH 0/2 V4] irqchip: gic: Introduce ARM GICv2m MSI(-X) support

[suravee.suthikulpanit at amd.com]

From: Suravee Suthikulpanit <Suravee.Suthikulpanit at amd.com>

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

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 V4:
    * Rebase to git://git.infradead.org/users/jcooper/linux.git irqchip/core
    * Remove patch 2 from previous version
    * Merge patch 1 and 3 from previous version
    * Reworks the GICv2m initialization based on Marc Zyngier review comments.
    * Introduce "v2m" subnode in GIC binding
    * Moves the "struct msi_chip" from "struct gic_chip_data" to "struct v2m_data".
