[U-Boot] [PATCH 03/53] binman: Move GetFdtSet() into blob_dtb

[Simon Glass]

At present we check the filename to see if an entry holds a device-tree
file. It is easier to use the base class designed for this purpose.

Move this method implementation into Entry_blob_dtb and update the default
one to return an empty set.
