That's not quite the same.  clocksource_calc_mult_shift() was introduced
in November 2009, whereas clocksource_register_hz() was introduced in
May 2010.  I'm updating everything to the latest interface.

The newer interface removes the burden of having to figure out what to
pass as the 'minsec' parameter, as well as simplifying the clocksource
registration code down to one line.
