[PATCH 09/10] sparc: Convert to using clocksource_register_hz()

[John Stultz <john.stultz@linaro.org>]

While cleaning up some clocksource code, I noticed the
time_32 impelementation uses the hz2mult helper, but
doesn't use the clocksource_register_hz() method.

I don't believe the sparc clocksource is a default
clocksource, so we shouldn't need to self-define
the mult/shift pair.

So convert the time_32.c implementation to use
clocksource_register_hz().

Untested.
