The tidss crtc driver implements its own state, with its own
implementation of reset and duplicate_state, but uses the default
destroy_state helper.
This somewhat works for now because the drm_crtc_state field in
tidss_crtc_state is the first field so the offset is 0, but it's pretty
fragile and it should really have its own destroy_state implementation.
