clocksource: Allow unregistering the watchdog
[ Upstream commit bbf66d897adf2bb0c310db96c97e8db6369f39e1 ]
Hyper-V vmbus module registers TSC page clocksource when loaded. This is
the clocksource with the highest rating and thus it becomes the watchdog
making unloading of the vmbus module impossible.
Separate clocksource_select_watchdog() from clocksource_enqueue_watchdog()
and use it on clocksource register/rating change/unregister.
After all, lobotomized monkeys may need some love too.
