Uwe Kleine-König 6a8f359c31 gpio: pca953x: Make platform teardown callback return void
All platforms that provide a teardown callback return 0. New users are
supposed to not make use of platform support, so there is no
functionality lost.

This patch is a preparation for making i2c remove callbacks return void.
