If gicv4.1(sgi hardware injection) supported, we test ipi injection

nit: active-less SGIs are not strictly a feature of GICv4.1 (you could
imagine a GIC emulation offering the same thing). Furthermore, GICv4.1
isn't as such visible to the guest itself (it only sees a GICv3).

By the way, I have just downloaded the latest GIC spec from the ARM
portal and I still do not find the GICD_CTLR_ENABLE_G1A,
GICD_CTLR_nASSGIreq and GICD_TYPER2_nASSGIcap. Do I miss something?

The latest spec still is the old one. There is a *confidential* erratum
to the spec that adds the missing bits, but nothing public.

You unfortunately will have to take my word for it.
