binman: Store the entry in output_fdt_files

In some cases we want to access the Entry object for a particular device
tree. This allows us to read its contents or update it. Add this
information to output_fdt_files and provide a function to read it.

Also rename output_fdt_files since its name is no-longer descriptive.
