These 2 files are in different kernel modules, the traces are defined twice in the kernel which leads to problem enabling only some traces. Move sensorhub traces from cros_ec_trace.h to cros_ec_sensorhub_trace.h and enable them only in cros_ec_sensorhub kernel module. Check we can now enable any single traces: without this patch, we can only enable all sensorhub traces or none.
