dm: pinctrl: Skip gpio-controller node in pinconfig_post_bind()
Some binding define child node gpio-controller without compatible property. This patch avoid to bind the pinconfig uclass to these node. For example, the binding for st,stm32-pinctrl (./device-tree-bindings/pinctrl/st,stm32-pinctrl.txt) defines the GPIO controller/bank node as sub-node of pincontrol (st,stm32f429-pinctrl) but without compatible (as it is not mandatory).
