rockchip: Remove pulls for gpio_output(), clean up code
Output GPIOs should never have a pull-up or pull-down resistor attached since they're actively driven. Since some GPIOs get initialized with a pull at power-on reset, we should explicitly overwrite that setting. Most other platforms do this on gpio_output, but Rockchip hadn't yet. Also, shuffle some code around to make things cleaner and allow for easier code reuse. BRANCH=None BUG=chrome-os-partner:52526 TEST=Booted Kevin.
