drm/zte: Use drm_mode_get_hv_timing() to populate plane clip rectangle
Use drm_mode_get_hv_timing() to fill out the plane clip rectangle. Note that this replaces crtc_state->adjusted_mode usage with crtc_state->mode. The latter is the correct choice since that's the mode the user provided and it matches the plane crtc coordinates the user also provided. Once everyone agrees on this we can move the clip handling into drm_atomic_helper_check_plane_state().
