powerpc: Update example SOC node in booting-without-of.txt. 



Convert to DTS version 1, eliminate some obsolete practices, and
correct some errors (compared to the actual 8540 device tree).

Appendix A - Sample SOC node for MPC8540

========================================



Note that the #address-cells and #size-cells for the SoC node

in this example have been explicitly listed; these are likely

not necessary as they are usually the same as the root node.
