drm/xe/ggtt: use drm_dev_enter to mark device section
Device can be hotunplugged before we start destroying gem objects. In such a case don't touch the GGTT entries, trigger any invalidations or mess around with rpm. This should already be taken care of when removing the device, we just need to take care of dealing with the software state, like removing the mm node. v2: (Andrzej) - Avoid some duplication by tracking the bound status and checking that instead.
