[PATCH v2 09/11] KVM: arm: disable debug mode if we don't actually need it.

Until now we enable debug mode all the time even if we don't actually need it. Inspired by the implementation in arm64, disable debug mode if we don't need it. And then we are able to reduce unnecessary registers saving/restoring when the debug mode is disabled. Signed-off-by: Zhichao Huang ---
