drm: Add __drm_atomic_helper_crtc_state_reset() & co.

Browse Source 
Annoyingly __drm_atomic_helper_crtc_reset() does two
totally separate things:
a) reset the state to defaults values
b) assign the crtc->state pointer

I just want a) without the b) so let's split out part
a) into __drm_atomic_helper_crtc_state_reset(). And
of course we'll do the same thing for planes and connectors.

v2: Fix conn__state vs. conn_state typo (Lucas)
    Make code and kerneldoc match for
    __drm_atomic_helper_plane_state_reset()
