KVM: arm64: vgic: Add Apple M2 cpus to the list of broken SEIS implementations
I really hoped that Apple had fixed their not-quite-a-vgic implementation
when moving from M1 to M2. Alas, it seems they didn't, and running
a buggy EFI version results in the vgic generating SErrors outside
of the guest and taking the host down.
Apply the same workaround as for M1. Yes, this is all a bit crap.
