[media] tc358743: set direction of reset gpio using devm_gpiod_get
Commit 256148246852 ("[media] tc358743: support probe from device tree") failed to explicitly set the direction of the reset gpio. Use the optional flag of devm_gpiod_get to make up leeway. This is also necessary because the flag parameter will become mandatory soon.
