rfnoc: Centralize initialization state of SEPs to epid_allocator

Because the initialization state of SEPs is a graph-wide property,
link_stream_managers and mgmt_portals cannot rely on their private
members to determine if they can reset an SEP. Move the call to
init SEPs into the epid_allocator, and have it call into a
mgmt_portal to gain access to the SEP.

Thus, link_stream_managers only request that an epid_allocator
ensure an SEP is numbered and initialized, and they provide a path
to communicate with the SEP. The epid_allocator will ensure init
only happens once, so a stream currently running on another
link_stream_manager does not get interrupted. This could happen,
for example, if the OSTRM went to one device, and the ISTRM came
from another. In general, EPIDs should only be assigned once.
