rfnoc: Use link_stream_manager's mgmt_portal for all mgmt packets

Change data transports to use the mgmt_portal from the
link_stream_manager. The initialization state of a device's EPIDs
needs to be shared amongst all the SEP users. Otherwise, an RX
transport may attempt to do a full reset of the SEP while TX is
streaming (for example).

TODO: The code contained here is not sufficient to handle multiple
links that can access the same SEPs, as those would have different
link_stream_managers, and thus, different mgmt_portal instances and
views of the SEP state.
