Subject: [PATCH v2] clocksource: fix misleading comment for __clocksource_updatefreq_scale()

Functions clocksource_updatefreq_hz() and clocksource_updatefreq_khz()
mentioned in the comment of __clocksource_updatefreq_scale() do not exist.

As Thomas Gleixner's suggestion, I renamed the functions and the few call
sites because the underscores are completely meaningless.
