For this one, the parser rejects an MI_STORE_REGISTER_MEM with the GGTT bit
set. We don't currently allow that, even from master. It sounds like there
might be released versions of the ddx that do this as well. If that's the
case, or if there are other situations where tests, etc rely on being able
to do whatever they want when setting the I915_DISPATCH_SECURE flag, then I
think we might as well stop parsing secure batches and let them go through
as before.

Thanks,
Brad
