suspend/resume callbacks via class->pm (dev_pm_ops) instead of Legacy
class->suspend/resume. When __device_suspend() runs call-backs, it will
find class->pm ops for the drm class.

drm_class_suspend() hook calls driver legacy ops with the state information.
e.g: drm_class_suspend() calls into driver suspend routines
via drm_dev->driver->suspend(drm_dev, state).

Once drm_class_suspend() is converted to dev_pm_ops, it will no longer

suspend calls. A new freeze and suspend hooks are added to address the not

simply call __drm_class_suspend() with the appropriate pm state information.
