clocksource, sparc32: Convert to using clocksource_register_hz()

Browse Source 
While cleaning up some clocksource code, I noticed the
time_32 implementation uses the clocksource_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.
