Analogously to 9358d755bd5c, this registers a broadcast clockevent in
case no hardware broadcast timer is available and the per-CPU timers can
be stopped in deep power states.

Partitions of the Jailhouse hypervisor fall in this category.
Registering the workaround timer allows to enter high-resolution mode in
that case.

Gentle ping, just to avoid that this falls through the cracks because
it's so small.

2nd ping. Should this patch be routed via ARM or rather some tip/timers

3rd try: Could someone have a look at this and merge it - or at least
ack it in order to move forward?

Still no reactions, so I'm kindly reminding of this patch again.
