sh: Fix up clockevents broadcasting.
This fixes up the clockevents broadcasting code as detailed in commit ee348d5a1d810bc9958cabb7c27302aab235d36e ("[ARM] realview: fix broadcast tick support"). This saves us from having to do strange ordering things with the broadcast clockevent device, relying on the rating instead. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
