gpio fixes for v6.18-rc5 

- use the firmware node of the GPIO chip, not its label for software
   node lookup
 - fix invalid pointer access in GPIO debugfs
 - drop unused functions from gpio-tb10x
 - fix a regression in gpio-aggregator: restore the set_config() callback
   in the driver
 - correct schema $id path in ti,twl4030 DT bindings
