From: Igor Opaniuk igor.opaniuk@toradex.com

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).

Extend the driver to build with DM_VIDEO enabled. DTS files must additionally include 'u-boot,dm-pre-reloc' property in soc and child nodes to enable driver binding to fsl_dcu_fb device.

Currently display timings aren't obtained from DT.
