imx233: add pinctrl debug code to track pin uses

Browse source 
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.
