coresight replicator: Cleanup programmable replicator naming
The Linux coresight drivers define the programmable ATB replicator as Qualcomm replicator, while this is designed by ARM. This can cause confusion to a user selecting the driver. Cleanup all references to make it explicitly clear. This patch : 1) Replace the compatible string for the replicator : qcom,coresight-replicator1x => arm,coresight-dynamic-replicator 2) Changes the Kconfig symbol (since this is not part of any defconfigs) CORESIGHT_QCOM_REPLICATOR => CORESIGHT_DYNAMIC_REPLICATOR 3) Improves the help message in the Kconfig. 4) Changes the name of the driver and the file : coresight-replicator-qcom => coresight-dynamic-replicator Cc: Pratik Patel <pratikp@codeaurora.org> Cc: Ivan T.
