[PATCH] KVM: arm64: vgic: Add Apple M2 PRO/MAX cpus to the list of broken SEIS implementations

[Marc Zyngier]

Unsurprisingly, the M2 PRO is also affected by the SEIS bug, so add it
to the naughty list. And since M2 MAX is likely to be of the same ilk,
flag it as well.

Tested on a M2 PRO mini machine.
