coresight: etmX.X: stm: Remove trace_id() callback
CoreSight sources provide a callback (.trace_id) in the standard source
ops which returns the ID to the core code. This was used to check that
sources all had a unique Trace ID.
Uniqueness is now gauranteed by the Trace ID allocation system, and the
check code has been removed from the core.
This patch removes the unneeded and unused .trace_id source ops
from the ops structure and implementations in etm3x, etm4x and stm.
