pinctrl: add function to retrieve range from pin
This adds a function to the pinctrl core to retrieve the GPIO range associated with a certain pin for a certain controller. This is needed when a pinctrl driver want to look up the corresponding struct gpio_chip for a certain pin. As the GPIO drivers can now create these ranges themselves, the pinctrl driver no longer knows about all its associated GPIO chips.
