video: fsl_dcu_fb: refactor init functions

Browse Source 
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).
