KVM: arm/arm64: vgic-new: Add IRQ sync/flush framework
Implement the framework for syncing IRQs between our emulation and the list registers, which represent the guest's view of IRQs. This is done in kvm_vgic_flush_hwstate and kvm_vgic_sync_hwstate, which gets called on guest entry and exit. The code talking to the actual GICv2/v3 hardware is added in the following patches.
