x86/tsc: Remove the unused check_tsc_disabled()
x86/tsc: Enumerate BXT tsc_khz via CPUID
x86/tsc: Enumerate SKL cpu_khz and tsc_khz via CPUID
x86/tsc_msr: Remove irqoff around MSR-based TSC enumeration
x86/tsc_msr: Add Airmont reference clock values
x86/tsc_msr: Correct Silvermont reference clock values
x86/tsc_msr: Update comments, expand definitions
