Forward accesses to the ICV_*SGI*_EL1 registers to EL1, and
emulate ICV_SRE_EL1 by returning a fixed value.

This should be enough to support GICv3 in a protected guest.

Out of curiosity, has the RVIC work / plans been dropped?

ARM has dropped the architecture, and it makes no sense
to move KVM to support non-architectural stuff.

Which means we will eventually have to harden the guest itself
to cope with the fact that it cannot trust the interrupt controller.

Yes, this is crap.
