Provide a helper to detect the enabled UART device during runtime. This lower the integration effort and make it more straight forward for 'simple' use-cases with a single UART enabled. If multiple UARTs are enabled the first enabled is returned. The auto-detection is enabled by setting IMX_BOOT_UART_BASE=0 to keep the backward compatibility. For more advanced use-cases (multiple UARTs are enabled) the user still has to provide the correct base address.
