Pull irq domain ARM updates from Thomas Gleixner:
"This set of changes make use of hierarchical irqdomains to provide:
- MSI/ITS support for GICv3
- MSI support for GICv2m
- Interrupt polarity extender for GICv1
Marc has come more cleanups for the existing extension hooks of GIC in
the pipeline, but they are going to be 3.20 material"
