KVM: VMX: Allow KVM_INTEL when building for Centaur and/or Zhaoxin CPUs

Browse Source 
Change the dependency for KVM_INTEL, i.e. KVM w/ VMX, from Intel CPUs to
any CPU that supports the IA32_FEAT_CTL MSR and thus VMX functionality.
This effectively allows building KVM_INTEL for Centaur and Zhaoxin CPUs.
