Add a clocksource id for kvm-clock, so that it can be identified through
enum clocksource_ids.
This will keep ptp_kvm working on x86 in the future, when
get_device_system_crosststamp() would be changed to compare enum
clocksource_ids, rather than struct clocksource *. It also makes
identifying kvm-clock easier for outside code in general.
