If we have stolen available, make use of it for ringbuffer allocation. Previously this was restricted to !llc platforms, as writing to stolen requires a GGTT mapping - but now that we have partial mappable support, the mappable aperture isn't quite so precious so we can use it more freely and ringbuffers are a good user for the otherwise wasted stolen.
