Presently the earlytimer probe handles the clockevents driver, which
requires that the clockevents driver be registered first. This bumps it
up by 1 to include the clocksource device, which can be safely ignored
if it doesn't exist, as we will simply error out on that path and defer
to the jiffies clocksource.
