Apparently, having ~1000 wired interrupts is not enough, and some
people need more. Fear not! The GIC Achitecture Department hereby
grants you another 1024 SPIs, together with 64 PPIs, provided that you
implement GICv3.1 (see [1] for the details)
This series implements the required support, which requires a bit of
infrastructure rework in order to make the thing less horrible...
This has been tested on a FastModel. If there is no additional issue being
reported, I plan to put this into -next toward the end of this week and
let it simmer there for a bit.

* From v1:
- Tighten ESPI range matching
- Added a warning to detect inconsistent distributor/cpu interface
configurations
- Added quirks to handle HIP06/07 erratum 161010803 which unexpectedly
advertise ESPI support
