* Function Name: main
********************************************************************************
* Summary:
* This is the main function of the CM33 non-secure application.
*
* It initializes the device and board peripherals. It also initializes the
* retarget-io middleware to be used with the debug UART port using which
* "Hello World!" is printed on the debug UART. The LED pin is initialized with
* default configurations. The CM55 core is enabled and then the programs enters
* an infinite while loop which toggles the LED1 with a frequency of 1 Hz.
*
* Parameters:
* none
*
* Return:
* int
