coresight: Rename nr_outports to nr_outconns

Rename to avoid confusion between port number and the index in the
connection array. The port number is already stored in the connection,
and in a later commit the connection array will be appended to, so
the length of it will no longer reflect the number of ports.

No functional changes.
