Use the correct old/new topology and payload states in
intel_mst_disable_dp(). So far drm_atomic_get_mst_topology_state() it
used returned either the old state, in case the state was added already
earlier during the atomic check phase or otherwise the new state (but
the latter could fail, which can't be handled in the enable/disable
hooks). After the first patch in the patchset, the state should always
get added already during the check phase, so here we can get the
old/new states without a failure.
drm_dp_remove_payload() should use time_slots from the old payload state
and vc_start_slot in the new one. It should update the new payload
states to reflect the sink's current payload table after the payload is
removed. Pass the new topology state and the old and new payload states
accordingly.
This also fixes a problem where the payload allocations for multiple MST
streams on the same link got inconsistent after a few commits, as
during payload removal the old instead of the new payload state got
updated, so the subsequent enabling sequence and commits used a stale
payload state.
v2: Constify the old payload state pointer. (Ville)

2.37.1
Add a function to get the old MST topology state, required by a
follow-up i915 patch.
While at it clarify the code comment of
drm_atomic_get_new_mst_topology_state() and add _new prefix
to the new state pointer to remind about its difference from the old
state.
v2: Use old_/new_ prefixes for the state pointers. (Ville)

2.37.1
Add the MST topology for a CRTC to the atomic state if the driver
needs to force a modeset on the CRTC after the encoder compute config
functions are called.
Later the MST encoder's disable hook also adds the state, but that isn't
guaranteed to work (since in that hook getting the state may fail, which
can't be handled there). This should fix that, while a later patch fixes
the use of the MST state in the disable hook.
v2: Add missing forward struct declartions, caught by hdrtest.
v3: Factor out intel_dp_mst_add_topology_state_for_connector() used
later in the patchset.
