x86/tsc: Handle CLOCK_SOURCE_VALID_FOR_HRES correctly
Unconditionally setting the CLOCK_SOURCE_VALID_FOR_HRES for the real TSC clocksource is wrong as there is no guarantee that the early TSC was validated for high resolution mode. Set the flag only when the early TSC was validated as otherwise the clocksource selection might enable high resolution mode with a TSC of unknown quality and possibly no way to back out once it is discovered to be unsuitable.
