KVM: arm64: nv: Add Maintenance Interrupt emulation
Emulating the vGIC means emulating the dreaded Maintenance Interrupt.
This is a two-pronged problem:
- while running L2, getting an MI translates into an MI injected
in the L1 based on the state of the HW.
- while running L1, we must accurately reflect the state of the
MI line, based on the in-memory state.
The MI INTID is added to the distributor, as expected on any
virtualisation-capable implementation, and further patches
will allow its configuration.
