[PATCH 18/25] drm: kirin: Move drm driver to driver data

From: John Stultz
Date: Tue Apr 23 2019 - 19:21:31 EST


From: Xu YiPing <xuyiping@xxxxxxxxxxxxx>

As part of refactoring the kirin driver to better support
different hardware revisions, this patch moves the drm_driver
structure to be under device specific driver data.

This will allow us to more easily add support for kirin960
hardware with later patches.
