[ 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.
