[PATCH v4 2/3] drm/i915: Refactor icl_is_hdr_plane

[Kevin Strasser <kevin.strasser@intel.com>]

Change the api in order to enable callers that can't supply a valid
intel_plane pointer, as would be the case prior to calling
drm_universal_plane_init.

v4:
- Rename variables and move a declaration (Ville)
