Subject: [PATCH 21/25] drm: kirin: Fix dev->driver_data setting

From: Xu YiPing <xuyiping@...ilicon.com>

As part of refactoring the kirin driver to better support
different hardware revisions, this patch changes the
dev->driver_data to point to a drm_device, not ade_data.

Thus we set the driver data to drm device after alloc.
