coresight-replicator: change replicator_drvdata spinlock's type to raw_spinlock_t

In coresight-replicator drivers, replicator_drvdata->spinlock can be held
during __schedule() by perf_event_task_sched_out()/in().

Since replicator_drvdata->spinlock type is spinlock_t and
perf_event_task_sched_out()/in() is called after acquiring rq_lock,
which is raw_spinlock_t (an unsleepable lock),
this poses an issue in PREEMPT_RT kernel where spinlock_t is sleepable.

To address this, change type replicator_drvdata->spinlock in
coresight-replicator drivers, which can be called
by perf_event_task_sched_out()/in(), from spinlock_t to raw_spinlock_t.
