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

Rob, what's your view on keeping the old binding around? We could simply change
the two occurences we find in the DTs (Juno and 410c) to the new name and be
done with the old one.

While at it, I would also change the name of the file.

Sure, will do.

Thanks
