A dummy timer is already installed unconditionally on devices with an
arm architected timer, so if this is breaking something then those
devices have been broken in the 3.9 merge window. I suppose we may need
to make the rating even lower if there is somebody using a clockevent
with a rating below 100. My grep of the tree shows 125 as the lowest,
but perhaps we want to set the rating to 1 to be safe?
