Revert "drm/display/dp_mst: Move all payload info into the atomic state"

This reverts commit 4d07b0bc.

[Why]
Changes cause regression on amdgpu mst.
E.g.
In fill_dc_mst_payload_table_from_drm(), amdgpu expects to add/remove payload
one by one and call fill_dc_mst_payload_table_from_drm() to update the HW
maintained payload table. But previous change tries to go through all the
payloads in mst_state and update amdpug hw maintained table in once everytime
driver only tries to add/remove a specific payload stream only. The newly
design idea conflicts with the implementation in amdgpu nowadays.

[How]
Revert this patch first. After addressing all regression problems caused by
this previous patch, will add it back and adjust it.
