x86/timers: Move the simple udelay calibration to tsc.h
Commit dd759d93f4dd ("x86/timers: Add simple udelay calibration") adds
an static function in x86 boot-time initializations.
But, this function is actually related to TSC, so it should be maintained
in tsc.c, not in setup.c.
Move simple_udelay_calibration() from setup.c to tsc.c and rename it to
tsc_early_delay_calibrate for more readability.
