Recent kvm has some basic support of hyperv, this will cause the guest to
identify itself as running on top of hyperv instead of kvm which will disable
kvm pv functionality. This is because we try to detect hyperv before kvm. Solve
this by simply checking kvm in detect_hypervisor() first.

This patch introduce hypervisor_cpuid_base() which loop test the hypervisor
existence function until the signature match and check the number of leaves if
required. This could be used by Xen/KVM guest to detect the existence of
