coresight: Fixes coresight DT parse to get correct output port ID.
[ Upstream commit eeedc5421dd3b51de73e6106405c5c77f920f281 ]
Corrected to get the port numbering to allow programmable replicator driver
to operate correctly.
By convention, CoreSight devices number ports, not endpoints in
the .dts files:-
port {
reg<N>
endpoint {
}
}
Existing code read endpoint number - always 0x0, rather than the correct
port number.
