This patch set adds MSI/MSIX termination driver support for APM X-Gene v1 SoC.
APM X-Gene v1 SoC supports its own implementation of MSI, which is not compliant
to GIC V2M specification for MSI Termination.
There is single MSI block in X-Gene v1 SOC which serves all 5 PCIe ports. This MSI
block supports 2688 MSI termination ports coalesced into 16 physical HW IRQ lines
and shared across all 5 PCIe ports.
v2 changes:
1. Use msi_controller structure
2. Remove arch hooks arch_teardown_msi_irqs and arch_setup_msi_irqs
