drm/atomic-helper: Implement subsystem-level suspend/resume
Provide subsystem-level suspend and resume helpers that can be used to
implement suspend/resume on atomic mode-setting enabled drivers.
v2: simplify locking, enhance kerneldoc comments
v3: pass lock acquisition context by parameter, improve kerneldoc
v4: - remove redundant code (already provided by atomic helpers)
(Maarten Lankhorst)
- move backoff dance from drm_modeset_lock_all_ctx() into suspend
helper (Daniel Vetter)
v5: handle potential EDEADLK from drm_atomic_helper_duplicate_state()
and drm_atomic_helper_disable_all() (Daniel Vetter)
