Now that we mark the object domains for having been restored from the hibernation image, we not need to flush everything during resume and can instead rely on the normal domain tracking to flush only when required. The only caveat here are objects that are pinned for use by the hardware, whose contents must be coherent for when the device resumes reading from then (shortly afterwards with the driver assuming the objects are in the correct domain).
