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) 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

Changes since V1:
- Since the driver doesn't use the compatible string, change the
recommended compatible string.
- Rename the driver file to coresight-dynamic-replicator.c
