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.
