[PATCH 01/12] coresight replicator: Cleanup programmable replicator naming

[Suzuki K Poulose]

The Linux coresight drivers define the programmable ATB replicator as
Qualcom 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) Adds a new compatible string for the same, retaining the old one for
    compatibility.
 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 :
	coresight-replicator-qcom => coresight-dynamic-replicator
