msm: clock-debug: Update debug_suspend feature for prepared state

If a clock is prepared and not enabled we don't print information
about that clock in the debug_suspend feature. Fix the code to
consider unprepared as the only case to bail out early and also
update the printk to display the prepare count and enable count.
