KVM: PPC: Book3S: Move vcore definition to end of kvm_arch struct 

When building KVM with a lot of vcores (NR_CPUS is big), we can potentially
get out of the ld immediate range for dereferences inside that struct.

Move the array to the end of our kvm_arch struct. This fixes compilation
issues with NR_CPUS=2048 for me.
