[POWERPC] Delete boot-cpu property from all DTS files

The 'linux,boot-cpu' property is obsolete, so remove it from all of the DTS
files and from booting-without-of.txt.  The boot CPU is actually defined in
the device tree header, and U-Boot sets that field.  The device tree compiler
also complains if the property exists.
