coresight replicator: Cleanup programmable replicator naming

Browse source 
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

This enables support for Qualcomm CoreSight link driver. The
programmable ATB replicator sends the ATB trace stream from the
ETB/ETF to the TPIUi and ETR.
This enables support for dynamic CoreSight replicator link driver.
The programmable ATB replicator allows independent filtering of the
trace data based on the traceid.
