[U-Boot-Users] [PATCH 2/3 u-boot-fdt] Minor code clean up.

[Jerry Van Baren <gvb.uboot@gmail.com>]

Declare the variable fdt properly as extern.
Call the "set_fn" function pointer the "short way" without the full
  dereferencing syntax.

Suggestions from Wolfgang G. and Timur, respectively.  Thanks, guys.
