drm/sti: make use of drm_of_component_probe

Browse Source 
Enhance the probing sequence by using the ports property of the
display-subsystem node.

That done, it becomes possible to handle the display-substem node
outside of the soc node within the device-tree and not have each IP
blocks as children of the display-subsystem node.
