Move code from ad-hoc fbdev callbacks into DRM client functions
and remove the old callbacks. The functions instruct the client
to poll for changed output or restore the display.
The DRM core calls both, the old callbacks and the new client
helpers, from the same places. The new functions perform the same
operation as before, so there's no change in functionality.
