KVM: arm64: vgic: Implement SW-driven deactivation
In order to deal with these systems that do not offer HW-based
deactivation of interrupts, let implement a SW-based approach:
- When the irq is queued into a LR, treat it as a pure virtual
interrupt and set the EOI flag in the LR.
- When the interrupt state is read back from the LR, force a
deactivation when the state is invalid (neither active nor
pending)
Interrupts requiring such treatment get the VGIC_SW_RESAMPLE flag.
