Michael Kelley 989e44d6d2 clockevents/drivers/i8253: Add support for PIT shutdown quirk ...

commit 35b69a420b upstream.

Add support for platforms where pit_shutdown() doesn't work because of a
quirk in the PIT emulation. On these platforms setting the counter register
to zero causes the PIT to start running again, negating the shutdown.

Provide a global variable that controls whether the counter register is
zero'ed, which platform specific code can override.
