Move dcu-related code to fsl_dcu_probe_common, keep in video_hw_init() only legacy video stack (filling GraphicPanel struct etc.). Add wrappers for all init functions, that will let to provide struct fb_info as an additional param (needed for further moving it from the global scope to driver private data struct in DM converted driver).
