drm/armada: Use drm_mode_get_hv_timing() to populate plane clip rectangle

Use drm_mode_get_hv_timing() to fill out the plane clip rectangle.

Since armada isn't atomic we'll use crtc->enabled and crtc->mode instead
of the stuff under crtc_state.

Once everyone agrees on how the clip rectangle gets set up we can
move the code into drm_atomic_helper_check_plane_state().
