x86/tsc: Split native_calibrate_cpu() into early and late parts
During early boot TSC and CPU frequency can be calibrated using MSR, CPUID,
and quick PIT calibration methods. The other methods PIT/HPET/PMTIMER are
available only after ACPI is initialized.
Split native_calibrate_cpu() into early and late parts so they can be
called separately during early and late tsc calibration.
