print_fourcc helper function was used for debug log to convert a pixel format code into its readable form for display purposes. But since it used a single static buffer to perform the conversion this might lead to display format issue when more than one instance was invoked simultaneously. Instead we make use of the new standard macros to log the fourcc value in a human readable format.
