[0/3] coresight: Alloc trace ID after building the path

Message

Proof of concept to support CTCU device. Applies to Jie's patchset in
the parent email. I think this would be a good simplification, it
removes some code and makes things a bit clearer, and works for both the
old and new CTCU requirements. It will require merging into the parent
patchset somehow as it undoes some of those changes.
