pinctrl: stm32: use valid pin identifier in stm32_pinctrl_resume()

commit c370bb474016ab9edfdabd7c08a88dd13a71ddbd upstream.

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.
