The GICv4.1 architecture gives the hypervisor the option to let the guest choose whether it wants the good old SGIs with an active state, or the new, HW-based ones that do not have one. For this, plumb the configuration of SGIs into the GICv3 MMIO handling, present the GICD_TYPER2.nASSGIcap to the guest, and handle the GICD_CTLR.nASSGIreq setting. In order to be able to deal with the restore of a guest, also apply the GICD_CTLR.nASSGIreq setting at first run so that we can move the restored SGIs to the HW if that's what the guest had selected in a previous life.
