drm/tilcdc: crtc: Use drm_atomic_helper_check_crtc_primary_plane()

In the tilcdc_crtc_atomic_check(), the tilcdc driver hand-crafts its own
implementation of drm_atomic_helper_check_crtc_primary_plane(). And it
does so by accessing the state pointer in drm_atomic_state->planes which
is deprecated.

Let's use the right helper here.
