ARM: mx5/babbage: Use gpio_request_one in babbage_fec_reset

Current code inside babbage_fec_reset uses gpio_direction_output with initial value of the GPIO and also sets
the GPIO value via gpio_set_value to the same level right after. This is not needed.

By using gpio_request_one it is possible to set the direction and initial value in one shot.
