[PATCH] ppc64: Fix issue with non zero boot cpu

Browse Source 
The new version of the flattened device tree passes the boot cpuid in the
header instead of via a linux,boot-cpu property.

We need to update the in kernel OF parsing code to do this, otherwise
machines with a non zero boot cpuid fail to come up.
