clocksource: Clean up clocksource_update_freq() functions

Browse Source 
Remove the unused functions __clocksource_update_freq_hz() and
__clocksource_update_freq_khz().

Then make __clocksource_update_freq_scale() static as it is not used
from external callers anymore. Also clean up the comment accordingly.
