coresight: etm3x: Update ETM3 driver to use Trace ID API
Use the TraceID API to allocate ETM trace IDs dynamically.
As with the etm4x we allocate on enable / disable for perf,
allocate on enable / reset for sysfs.
Additionally we allocate on sysfs file read as both perf and sysfs
can read the ID before enabling the hardware.
Remove sysfs option to write trace ID - which is inconsistent with
both the dynamic allocation method and the fixed allocation method
previously used.
