pinctrl: stm32: use valid pin identifier in stm32_pinctrl_resume()
When resuming from low power, the driver attempts to restore the configuration of some pins. This is done by a call to: stm32_pinctrl_restore_gpio_regs(struct stm32_pinctrl *pctl, u32 pin) where 'pin' must be a valid pin value (i.e. matching some 'groups->pin'). Fix the current implementation which uses some wrong 'pin' value.
