* \brief This function initializes the specified UART instance for use.
* This does the following:
* 1> Sets the baud rate of communication as 115200.
* 2> Configures the line characteristics to a typical value being
* 8-N-1 which means 8 data bits per frame, No parity bit and
* 1 stop bit/frame.
* 3> Enables the FIFO for transmitter and receiver.
* 4> Sets the receiver trigger level to be 1 byte.
*
* \return None.
*
* \note This function invokes UARTStdioInitExpClk() to perform the above
* configurations. The function UARTStdioInitExpClk() could be
* directly invoked for more customized configurations.
