Subject[RESEND][PATCH v3 14/26] drm: kirin: Move ade crtc/plane help functions to driver_data
Date
From: Xu YiPing <xuyiping@hisilicon.com>

As part of refactoring the kirin driver to better support
different hardware revisions, this patch moves the crtc
and plane funcs/helper_funcs to the struct kirin_drm_data.

This will make it easier to add support for new devices
via a new kirin_drm_data structure.
