Here's a respin of the NV support for GICv3. The integration branch
containing this (and the rest of the NV stack) is still at [2].
* From v1 [1]:
- Fix the default value for the MI INTID to PPI9, instead of
something fairly random...
- Fail KVM initialisation if asking for NV on HW without a virtual
GICv3.
