[PATCH 01/24] gtrace: Move connection release into component unregister

[Zane Leung]

Add gtrace_release_outconns() and call it from
gtrace_unregister_component() so the output connection fwnode
references are released in the core instead of being duplicated
in every platform driver's remove callback.
