Subject: [PATCH] mei: trace: Remove unused TRACE_SYSTEM_STRING define

TRACE_SYSTEM_STRING is defined in mei-trace.h but is unused. Worse yet,
the ftrace tracing infrastructure is using it now and this causes
warnings about redefined macros.

Remove the define of TRACE_SYSTEM_STRING from mei-trace.h
