x86/kvm, ptp/kvm: Add clocksource ID, set system_counterval_t.cs_id
Add a clocksource ID for the x86 kvmclock. Also, for ptp_kvm, set the recently added struct system_counterval_t member cs_id to the clocksource ID (x86 kvmclock or ARM Generic Timer). In the future, get_device_system_crosststamp() will compare the clocksource ID in struct system_counterval_t, rather than the clocksource. For now, to avoid touching too many subsystems at once, extract the clocksource ID from the clocksource. The clocksource dereference will be removed once everything is converted over..
