[ARM] 4814/1: RealView: Add broadcasting clockevents support for ARM11MPCore
This patch adds dummy local timers for each CPU so that the board clock
device is used to broadcast events to the other CPUs. The patch also
adds the declaration for the dummy_timer_setup function (the equivalent
of local_timer_setup when CONFIG_LOCAL_TIMERS is not set).
Due to the way clockevents work, the dummy timer on the first CPU has to
be registered before the board timer.
