Subject: [PATCH 0/2] STM32 enable gpio irqs as wakeup irqs for uart port

This patchset allows to use mctrl_gpio pins as wakeup source.
Add a new API to enable / disable wake_irq for serial mctrl_gpio pins.
Use this API in STM32 usart driver to enable / disable mctrl_gpio pins
wake_irq in suspend / resume procedure.
