This patch removes the apply() manager callback in favor of putting the relevant commits in the individual drivers. This will mitigate some of the difference between the suspend/resume path and the dpms path

Changes in v2: - This was previously in another patch, but moved since it warrants its own Changes in v3: - Removed apply() from vidi Changes in v4: None
