drm: kirin: Move config max_width and max_height to driver data

As part of refactoring the kirin driver to better support
different hardware revisions, this patch moves the max_width
and max_height values used in kirin_drm_mode_config_inita to
hardware specific driver data.

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