Bind only the enabled GPIO subnode, to avoid to probe the node "gpio-controller" present in SOC dtsi (disabled by default) but not enabled in the included pincontrol dtsi file.
For example, in stm32mp15xxac-pinctrl.dtsi 2 gpio bank are absent: gpioj: gpio@5000b000 gpiok: gpio@5000c000
Then these GPIO are absent in output of command "dm tree" and "gpio status -a"
