drm: kirin: Rename ade_plane to kirin_plane

Browse source 
As part of refactoring the kirin driver to better support
different hardware revisions, this patch renames the
struct ade_plane to kirin_plane.

The struct kirin_plane will later used by both kirin620 and
future kirin960 driver, and will be moved to a common
kirin_drm_drv.h in a future patch
