qemu-options: Remove deprecated -no-kvm-irqchip

We've never documented this option in our qemu-doc, so apart from the users
that already used the old qemu-kvm fork before, most users should not be
aware of this option at all. It's been marked as deprecated in the source
code for a long time already, and officially marked as deprecated in the
documentation since QEMU v2.10, so it should be fine to remove this now.
