drm: kirin: Move ade drm init to kirin drm drv
As part of refactoring the kirin driver to better support different hardware revisions, this patch renames ade_data to kirin_drm_private, and moves crtc_init and plane_init to kirin drm drv too. Now that they are generic the functions can be shared between the kirin620 and (to be added later) kirin960 specific support code.
