[PATCH] arm: dts: imx7: Fix error in coresight TPIU graph connection

OF graph endpoint connections must be bidirectional and dtc will now
warn if they are not. i.MX7 based DTs have an error and generate
warnings:

Warning (graph_endpoint): /replicator/ports/port at 0/endpoint: graph connection to node '/soc/tpiu at 30087000/port/endpoint' is not bidirectional
Warning (graph_endpoint): /soc/tpiu at 30087000/port/endpoint: graph connection to node '/replicator/ports/port at 1/endpoint' is not bidirectional

This appears to be a copy-n-paste error and the TPIU input should be
connected to replicator port 0 instead of port 1.
