pps: make pps-producer RT only on freedreno

Calling sched_setscheduler twice every sample period has high CPU
overhead.  For intel and panfrost, their dump_perfcnt is preemptible and
they don't need the scheduler change.

For freedreno, simply makes the main thread RT at all time.  This solves
most of the cpu overhead issue.

v2: removed pthread_t param and just change the scheduler for the
    calling thread
