We do not want to maintain this option forever. It will be removed after
a grace period of a few releases. So warn the user that this option has
no effect and will become invalid soon.

As discussed on yesterdays qemu call, follows qemu-kvm compat patches
for qemu:
- command line compatibility
- allow configurable ram size for cirrus
Allow RAM size to be configurable for cirrus, to allow migration
compatibility from qemu-kvm.

Upstream is moving towards this mechanism, so start using it in qemu-kvm
already to configure the specific defaults: kvm enabled on, just like
