Add a feature for automatically finding and loading a dtb file by name.
The name is taken from the u-boot env vars fdtfile or fdt_file.  If the
name isn't fully-qualified a search is done in module_path locations.

The search order for a usable dtb in fdt_setup_fdtp() is now

 - A dtb loaded with an explicit "load -t dtb" command.
 - A dtb already loaded into memory somehow[*] and pointed to by fdt_to_load.
 - A dtb in the memory pointed to by the u-boot env vars fdtaddr or fdt_addr.
 - A file named by the u-boot env vars fdtfile or fdt_file.
 - A static dtb compiled into the kernel.

* Presumably by some arch-specific command or code.
