From: Xu YiPing xuyiping@hisilicon.com
As part of refactoring the kirin driver to better support different hardware revisions, this patch moves the number of planes and the primary plane value to the kirin_drm_data structure
This will make it easier to add support for new devices via a new kirin_drm_data structure.
