coresight: change coresight_trace_id_map's lock type to raw_spinlock_t
coresight_trace_id_map->lock can be acquired while coresight devices'
drvdata_lock.
But the drvdata_lock can be raw_spinlock_t (i.e) coresight-etm4x.
To address this, change type of coresight_trace_id_map->lock to
raw_spinlock_t
