drm: kirin: Move plane number and primay plane in driver data 

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.
