Three regressions 

- Revert frame counter support
   . This patch fixes a issue which doesn't work extension and clone
     mode because some CRTC devices don't provide frame counter value
     properly.
 - Fix lack of fbdev on Rinato and trats boards.
   . This patch considers for connector to be registered by DSI after
     DRM device is registered, and also it makes fbdev initializaion
     to be done even if no connector at the moment.
 - Check for dsi->panel object correctly
   . This patch fixes checking for dsi->panel. of_drm_find_panel
     function returns panel object or error value so error value
     should be checked using IS_ERR macro.
