drm/tidss: crtc: Cleanup reset implementation
The tidss_crtc_reset() function will (rightfully) destroy any pre-existing state. However, the tidss CRTC driver has its own CRTC state structure that subclasses drm_crtc_state, and yet will destroy the previous state by calling __drm_atomic_helper_crtc_destroy_state() and kfree() on its drm_crtc_state pointer. It works only because the drm_crtc_state is the first field in the structure, and thus its offset is 0. It's incredibly fragile however, so let's call our destroy implementation in such a case to deal with it properly.
