It seems that we will have more and more pin controllers that support PWM function on the (selected) pins. Due to it being a part of pin controller IP the idea is to have some code that will switch the mode and attach the corresponding driver, for example, via using it as a library. Meanwhile, put a corresponding item to the pin_config_param enumerator.
