Subject[PATCH linux-next 2/2] x86/xen/time: cleanup xen_tsc_safe_clocksource
Modifies xen_tsc_safe_clocksource() to use newly defined constants from
arch/x86/include/asm/xen/cpuid.h. This replaces a numeric value with
XEN_CPUID_TSC_MODE_NEVER_EMULATE, and deletes a comment that is now self
explanatory.

There should be no change in the function's behavior.
