KVM: PPC: Add devname:kvm aliases for modules
Systems that support automatic loading of kernel modules through device aliases should try and automatically load kvm when /dev/kvm gets opened. Add code to support that magic for all PPC kvm targets, even the ones that don't support modules yet. Signed-off-by: Alexander Graf <agraf@suse.de>
