[POWERPC] mpc5200: add #address-cells and #size-cells to soc node.

The various 5200 dts files don't have values specified for the soc
node, which in turn results in a warning from the processing of
every child node (roughly 40 warnings per file).  This explicitly
sets the default values and gets rid of all the warnings.
