gpio: pcf857x: Make teardown callback return void
All teardown functions return 0. Also there is little sense in returning
a negative error code from an i2c remove function as this only results in
emitting an error message but the device is removed nevertheless.
This patch is a preparation for making i2c remove callbacks return void.
