pinctrl: stm32: Unshadow np variable in stm32_pctl_probe()
The np variable is used globally for stm32_pctl_probe() and in one of its code branches. cppcheck is not happy with that: pinctrl-stm32.c:1530:23: warning: Local variable 'np' shadows outer variable [shadowVariable] Instead of simply renaming one of the variables convert some code to use a device pointer directly.
