[PATCH 4/6] Input: adp5589: remove setup/teardown hooks for gpios

From: Alexandru Ardelean
Date: Wed Nov 11 2020 - 03:43:48 EST


This is currently just dead code. It's from around a time when
platform-data was used, and a board could hook it's own special callback
for setup/teardown, and a private object (via 'context').

This change removes it, as there are no more users in mainline for this.
