KVM: PPC: Add pt_regs into kvm_vcpu_arch and move vcpu->arch.gpr[] into it

Browse Source 
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.
