Subject: [PATCH v4 15/25] drm: kirin: Move mode config function to driver_data

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

As part of refactoring the kirin driver to better support
different hardware revisions, this patch moves the mode config
initialization values into the kirin_drm_data structure.

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