[S3C-CLK] ARM: S3C64XX: Avoid announcing clksrc clocks twice

[ben-linux@fluff.org (Ben Dooks)]

The new code calls the clock setup code on registration which
can be before the clock system has been fully initialised. The
following code re-does this setup at the end of the clock
registration and thus we get two printings.

Update the calls to only print on the last pass or when doing
the necessary resume work.
