Extend logging on TMC start / stop errors
Recent issues with trying to debug TMC timeouts and flush issues shows a general lack of logging and context around the possible errors
Add logging to general wait for stop coresight routines and return values of watched registers.
Update TMC to use this logging.
Changes since v1: Rebase to coresight/next (kernel 6.13-rc2)
Mike Leach (3): coresight: Update timeout functions to allow return of test register value coresight: tmc: Update error logging in tmc common functions coresight: etf: etr: Update logging around flush_and_stop() errors
