By using IOMUX instead of GPIO Matrix for UART, it is now possible on ESP32 boards to use the UART as a wake up source even if it is not used as a console. For other boards where this issue was not present, using IOMUX has the advantage to be faster than using GPIO matrix, so a highest baudrate can be used
