[PATCH 1/2] powerpc: publish 85xx soc dts entries as of_device

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.

The memory controller, L2 cache-controller, and the PCI controller(s) are
published as of_device so the mpc85xx EDAC driver can claim them for usage.

You don't need this if you make the change below.

Same as above.

Publish the devices listed in dts under SOC as of_device for mpc85xx_cds
platforms.

The memory controller, L2 cache-controller, and the PCI controller(s) are
published as of_device so the mpc85xx EDAC driver can claim them for usage.
