arm64: dts: juno: update definition for programmable replicator
Juno platforms have a programmable replicator splitting the trace output to TPIU and ETR. Currently this is not being programmed as it is being treated as a none-programmable replicator - which is the default operational mode for these devices. The TPIU in the system is enabled by default, and this combination is causing back-pressure in the trace system resulting in overflows at the source. Replaces the existing definition with one that defines the programmable replicator, using the "qcom,coresight-replicator1x" driver that provides the correct functionality for CoreSight programmable replicators.
