timer_list: print cpu number of clockevents device
The per cpu clock events device output of timer_list lacks an association of the device to the cpu which is annoying when looking at the output of /proc/timer_list from a 128 way system. Add the CPU number info and mark the broadcast device in the device list printout. Signed-off-by: Thomas Gleixner <tglx@linutronix.de>
