video: s3c-fb: Make runtime PM functional again The change in "video: s3c-fb: modify runtime pm functions" (commit 35784b) renders the runtime power management for the device completely ineffectual as while it leaves runtime power management notionally enabled a runtime power reference is held for the entire time the device is registered meaning it will never actually do anything. A further issue is introduced as runtime power management is added during the system suspend path which is not something which drivers are supposed to do and would interact poorly if there were any operations done in the runtime power management callbacks. While this does make things simpler (the main motivation for the original change) it will not only cause us to use more power in the framebuffer controller but will also prevent us entering lower power domain and SoC wide states as we can never power down the domain containing the device. Since neither of these things is desirable revert the change.
