kvm: Introduce core services for in-kernel irqchip support
Add the basic infrastructure to active in-kernel irqchip support, inject interrupts into these models, and maintain IRQ routes. Routing is optional and depends on the host arch supporting KVM_CAP_IRQ_ROUTING. When it's not available on x86, we looe the HPET as we can't route GSI0 to IOAPIC pin 2. In-kernel irqchip support will once be controlled by the machine property 'kernel_irqchip', but this is not yet wired up. Signed-off-by: Jan Kiszka <jan.kiszka@siemens.com>
