[PATCH] powerpc: publish 85xx soc dts entries as of_device on cds and ads platforms

[Dave Jiang]

Publish the devices listed in dts under SOC as of_device just like what
mpc85xx_mds platforms do. The 85xx cds and ads platforms currently do not
export the devices in dts as of_device.

I need the memory controller, L2 cache-controller, and the PCI controller
published as of_device so the mpc85xx EDAC driver can claim them for usage.

The mpc85xx EDAC driver can be found at:
http://bluesmoke.sourceforge.net/

It's in development to be pushed into the kernel.
