KVM: arm/arm64: vgic: Allow HW interrupts for non-shared devices
So far, the only use of the HW interrupt facility is the timer,
implying that the active state is context-switched for each vcpu,
as the device is is shared across all vcpus.
This does not work for a device that has been assigned to a VM,
as the guest is entierely in control of that device (the HW is
not shared). In that case, it makes sense to bypass the whole
active state switching, and only track the deactivation of the
interrupt.
