MFC r262326 (white space) and r262327 (fdt_addr).

This change was supposed to be whitespace only, but a functional change
snuck in, as follows:

  Look for both fdtaddr and fdt_addr env var names.  Grepping the u-boot
  source shows that board vendors seem to be about evenly split on this.
  The added lines were:

    /* Board vendors use both fdtaddr and fdt_addr names.  Grrrr. */

    if (s == NULL)
        s = ub_env_get("fdt_addr");
