[RFC PATCH 07/16] target/arm/kvm: Select RME VM type for the scratch VM

[Jean-Philippe Brucker <jean-philippe@linaro.org>]

Although the VM type does not affect values probed from the scratch vCPU
at the moment, it could later. Ensure we specify the right type when
creating the temporary VM.

Does the PA size need changing as well?
