Provide the user with configuration control over the cpu virtualization support in Xen by making AMD_SVM and INTEL_VMX options user selectable. To preserve the current default behavior, both options depend on HVM and default to Y. To prevent users from unknowingly disabling virtualization support, make the controls user selectable only if EXPERT is enabled. No functional change intended.
