x86/UV: Lower UV rtc clocksource rating
Lower the rating of the UV rtc clocksource to just below that of the tsc, to improve performance. Reading the tsc clocksource has lower latency than reading the rtc, so favor it in situations where it is synchronized and stable. When the tsc is unsynchronized, the rtc needs to be the chosen clocksource.
