binman: Add an FDT map
An FDT map is an entry which holds a full description of the image

its start. Tools can locate and read this entry to find out what entries
are in the image and where each entry is located.

+Alternatively, an FDT map entry can be used to add a special FDT containing
+just the information about the image. This is preceded by a magic string so can
