MLK-16688 driver: media: mxc_jpeg: Remove the unused function to kill the build warnnings

The patch fixes the following build warnnings by removing unused function:

drivers/media/platform/imx8/mxc-jpeg.c:228:13: warning: ‘print_output’ defined
but not used [-Wunused-function]
 static void print_output(void *addr)
             ^~~~~~~~~~~~

This patch also does the minor clean up by removing some commented-out code
