[PATCH 06/12] gpio: tpic2810: remove unneeded callbacks

[Bartosz Golaszewski]

From: Bartosz Golaszewski <bartosz.golaszewski@xxxxxxxxxx>

GPIO core can handle output-only chips that don't implement the get()
and direction_input() callbacks. There's no need to provide dummy
implementation of the latter in the driver so drop it.
