Why don't we just grow the FDT on demand, after we make sure that it always  
lives someplace that is safely growable?

Or if we absolutely must resize it all at once, have a variable that
contains the size required, which gets increased by whatever init code
determines a reason for it (whether it be QE firmware in this environment
variable, some other firmware in that environment variable, just a bunch of
nodes that u-boot creates on this platform, etc).
