[PATCH 1/2] gpio: rockchip: Call pinctrl for gpio config

[Matthijs Kooijman <matthijs@stdin.nl>]

Pinctrl is responsible for bias settings and possibly other pin config,
so call gpiochip_generic_config to apply such config values. This might
also include settings that pinctrl does not support, but then it can
return ENOTSUPP as appropriate.

This makes sure any bias and other pin config set by userspace (via
gpiod) actually takes effect.
