[PATCH v9 02/11] drm/panfrost: Don't sync rpm suspension after mmu flushing

[Dmitry Osipenko]

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.
