From: Xu YiPing xuyiping@hisilicon.com
As part of refactoring the kirin driver to better support different hardware revisions, this patch changes the code via a passed in driver_data pointer, rather than hardcoding them via ade_driver_data variable.
This will allow those funcitons to be later moved to the generic kirin_drm_drv.c using alternative driver_data structures that support other hardware.
