Master voltage regulation with MIC24045 and ATmega328P

/*!
 * \file 
 * \brief Mic24045 Click example
 * 
 * # Description
 * This example demonstrates the use of MIC24045 Click board.
 *
 * The demo application is composed of two sections :
 * 
 * ## Application Init 
 * Initializes the driver and enables the voltage output.
 * 
 * ## Application Task  
 * Changes the voltage output every 2 seconds and displays the current set value
 * on the USB UART.
