tracing/drm: Remove unused TRACE_SYSTEM_STRING define

The tracing infrastructure is adding a macro TRACE_SYSTEM_STRING, and hit the following build failure: In file included from include/trace/define_trace.h:90:0, from drivers/gpu/drm/.//radeon/radeon_trace.h:209, from drivers/gpu/drm/.//radeon/radeon_trace_points.c:9: >> include/trace/ftrace.h:28:0: warning: "TRACE_SYSTEM_STRING" redefined #define TRACE_SYSTEM_STRING __app(TRACE_SYSTEM_VAR,__trace_system_name) Seems that the DRM folks have added their own use to the TRACE_SYSTEM_STRING, with: #define TRACE_SYSTEM_STRING __stringify(TRACE_SYSTEM) Although, I can not find its use anywhere. I could simply use another name, but if this macro is not being used, it should be removed.
