KVM: arm/arm64: vgic: Signal IRQs using their configured group
Now when we have a group configuration on the struct IRQ, use this state when populating the LR and signaling interrupts as either group 0 or group 1 to the VM. Depending on the model of the emulated GIC, and the guest's configuration of the VMCR, interrupts may be signaled as IRQs or FIQs to the VM.
