[PATCH 4/4] x86/tsc: set TSC_KNOWN_FREQ and TSC_RELIABLE flags on Intel Atom SoCs

TSC on Intel Atom SoCs capable of determining TSC frequency by MSR is reliable and the frequency is known (because it's provided by HW). On these platforms PIT/HPET is generally not available so calibration won't work at all and also TSC is the only reliable clocksource. So we set both X86_FEATURE_
