drm/amdgpu/display/mst: limit payload to be updated one by one
[Why]
amdgpu expects to update payload table for one stream one time
by calling dm_helpers_dp_mst_write_payload_allocation_table().
Currently, it get modified to try to update HW payload table
at once by referring mst_state.
[How]
This is just a quick workaround. Should find way to remove the
temporary struct dc_dp_mst_stream_allocation_table later if set
struct link_mst_stream_allocatio directly is possible.
