[PATCH V2 1/2] target-arm: KVM64: Get and Sync up guest register state like kvm32.

[Pranavkumar Sawargaonkar <pranavkumar@xxxxxxxxxx>]

This patch adds:
1. Call write_kvmstate_to_list() and write_list_to_cpustate()
   in kvm_arch_get_registers() to sync guest register state.
2. Call write_list_to_kvmstate() in kvm_arch_put_registers()
   to sync guest register state.

These changes are already there for kvm32 in target-arm/kvm32.c.
