gpio: aggregator: remove the software node when deactivating the aggregator

Browse Source 
The dynamic software node we create for the aggregator platform device
when using configfs is leaked when the device is deactivated. Destroy it
as the last step in the tear-down path.

Fixes: 86f162e73d ("gpio: aggregator: introduce basic configfs interface")
