Suzuki K Poulose 5eb3a0c2c5 coresight: etm4x: Do not save/restore Data trace control registers 
ETM4x doesn't support Data trace on A class CPUs. As such do not access the
Data trace control registers during CPU idle. This could cause problems for
ETE. While at it, remove all references to the Data trace control registers.

Fixes: f188b5e76aae ("coresight: etm4x: Save/restore state across CPU low power states")
