serial: st-asc: Use new GPIOD API to obtain RTS pin
The commits mentioned below adapt the GPIO API to allow more information
to be passed directly through devm_get_gpiod_from_child() in the first
instance. This facilitates the removal of subsequent calls, such as
gpiod_direction_output(). This patch firstly moves to utilise the new
API and secondly removes the now superfluous call do set the direction.
