Wei Liu 7d4163c831 clocksource/hyperv: use MSR-based access if running as root 
When Linux runs as the root partition, the setup required for TSC page
is different. Luckily Linux also has access to the MSR based
clocksource. We can just disable the TSC page clocksource if Linux is
the root partition.
