Except for software sources (e.g. STM), other sources treat multiple enables as equivalent to a single enable. The device mode already tracks the binary state, so it is redundant to operate refcount. Introduce a helper coresight_is_software_source() for check software source. Refactor to maintain the refcount only for software sources. This simplifies future CPU PM handling without refcount logic.
