KVM: PPC: Add pt_regs into kvm_vcpu_arch and move vcpu->arch.gpr[] into it
Current regs are scattered at kvm_vcpu_arch structure and it will be more neat to organize them into pt_regs structure. Also it will enable reimplementation of MMIO emulation code with analyse_instr() later. Signed-off-by: Simon Guo <wei.guo.simon@gmail.com> Signed-off-by: Paul Mackerras <paulus@ozlabs.org>
