Otherwise, we end up filling out all of DC's link information with zeroes. So, let's restore that and hopefully fix this DSC regression.

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.

The above isn't always correct, as vc_start_slot must be the up-to-date version contained in the new payload state, but time_slots must be the one used when the payload was previously added, contained in the old payload state. The new payload's time_slots can change vs. the old one if the current atomic commit changes the corresponding mode. This patch let's drivers pass the old and new payload states to drm_dp_remove_payload(), but keeps these the same for now in all drivers not to change the behavior. A follow-up i915 patch will pass in that driver the correct old and new states to the function.
