Please could you let me know your thoughts on this ? Coresight PMU would
use this to inform the dynamically allocated trace id for a CPU to the
perf via this HWID packet.

If you are happy with the above change, I could pick it up via the
coresight tree with your Ack. Otherwise, please could you pick it
up ?
