The current check for default dtb image checks if the file exists and is
not empty but appends a slash to the path due to which the file is never
found. It also doesn't replace slash in filename with _ as done when
populating the DTB variable. A better way to check the existence of the
device tree would be from the list of DTBs since this is used during
compilation.
