drm/panfrost: Don't sync rpm suspension after mmu flushing
[ Upstream commit ba3be66f11c3c49afaa9f49b99e21d88756229ef ]
Lockdep warns about potential circular locking dependency of devfreq
with the fs_reclaim caused by immediate device suspension when mapping is
released by shrinker. Fix it by doing the suspension asynchronously.
