drm: kirin: Move channel formats to driver data

Browse source 
As part of refactoring the kirin driver to better support
different hardware revisions, this patch moves the channel
format arrays into the kirin_drm_data structure.

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