Mark Johnston 553af8f1ec x86: Perform late TSC calibration before LAPIC timer calibration
This ensures that LAPIC calibration is done using the correct tsc_freq
value, i.e., the one associated with the TSC timecounter.  It does mean
though that TSC calibration cannot use sbinuptime() to read the
reference timecounter, as timehands are not yet set up.
