the old FLAT_TREE u-boot fdt fixup code renames any existing chosen
node out of the way, and adds its fixed up version as /chosen.

The LIBFDT implementation replaces any existing /chosen with its fixed
up version.

So it all works out.  Adding chosen/linux,stdout-path properties to the
kernel dtses is fine.

btw, why are these changes being limited to the ITX and GP?
