imx233: add pinctrl debug code to track pin uses
Past development has proved that one can mistakely use the same pin for two uses without noticing. Since this causes extremely hard to find bugs, the infrastructure will allow to register pin uses and panic when a conflict is detected. The pinctrl debug now shows the pin uses when its support is compiled in. Change-Id: Idb2d5235ce09207d77aa474d6f158e72b933761a
