In this patch seried, modified kvm selftests code to enable guest code to run in vEL2(As guest Hypervisor). Also added test cases to test guest code booting in vEL2 and register access of VNCR mapped registers. This patchset is created as per discussions over ml[1]. Posting RFC patch for the early feedback and to further explore requirements and test cases.
