soc/*: mp_run_on_all_cpus: Remove configurable timeout
Some timeouts given were too small when serial console is enabled due to
its spinlock making code runtime worse with every AP present.
In addition we usually don't know how long specific code runs and how
long ago it was sent to the APs.
Remove the timeout argument from mp_run_on_all_cpus and instead wait up
to 1 second, to prevent possible crashing of secondary APs still
processing the old job.
Tested on Supermicro X11SSH-TF.
