[U-Boot] [PATCH 2/5] dm: video: bridge: don't fail to activate bridge if sleep gpio is missing

From: Vasily Khoruzhick <anarsoul at gmail.com>

Sleep gpio is optional, so it's possible to have reset gpio, but no sleep gpio.
We shouldn't fail early in case of missing sleep gpio, otherwise we won't
deassert reset.
