x86/tsc: Remove unused "US_SCALE" and "NS_SCALE" leftover macros
Last use of them was removed 13 years ago, when the code was converted
to use CYC2NS_SCALE_FACTOR:
53d517cdbaac: ("x86: scale cyc_2_nsec according to CPU frequency")
The current TSC code uses the 'struct cyc2ns_data' scaling abstraction,
the old fixed scaling approach is long gone.
This cleanup also removes the 'arbitralrily' typo from the comment,
so win-win. ;-)
