[PATCH 24/25] drm: kirin: Pass driver data to crtc init and plane init

[John Stultz]

From: Xu YiPing <xuyiping@xxxxxxxxxxxxx>

As part of refactoring the kirin driver to better support
different hardware revisions, this patch changes funcitons
to pass the kirin_driver_data as a prameter.

This will allow those funcitons to be later moved to the
generic kirin_drm_drv.c
