[RFC] powerpc/boot: add kernel,end node to the cuboot target

[Sebastian Siewior <bigeasy@linutronix.de>]

this could be used by the kexec userland code.

This is done by the 64bit kexec code allready. The 32bit doesn't use the
device tree at all. I'm not sure whether the node has to be a 32bit or
64bit value.
