[PATCH] drm/bridge: ti-sn65dsi86: remove unnecessary GPIO line direction check

[Bartosz Golaszewski]

From: Bartosz Golaszewski <bartosz.golaszewski at linaro.org>

As of commit 92ac7de3175e3 ("gpiolib: don't allow setting values on input
lines"), the GPIO core makes sure values cannot be set on input lines.
Remove the unnecessary check.
