We already have __drm_atomic_helper_connector_reset() and
__drm_atomic_helper_plane_reset(), extend this to crtc as well.

This will allow us to set default values in the crtc_state, without
having to do it in each driver separately.

Of all drivers that need conversion, only nouveau is done in this
commit, because it wrote its own __drm_atomic_helper_crtc_reset(),
clashing with the drm core.
