Enable System Configuration Controller clock in clock_control instead of gpio controller when we set a gpio as interrupt. We use System Configuration Controller to manage external interrupts and internal voltage reference for 48 MHz HSI used in USB device. Signed-off-by: Yannis Damigos <giannis.damigos@gmail.com>
