drivers: pinctrl: add support for dynamic pin control

Add support for dynamic pin control, that is, allow to change device pin
configuration at runtime. Because no device de-initialization is
available yet, this API has limited usage options, e.g. modify pin
configuration at early boot stage (before device driver is initialized)
