Ingo Molnar 716c69feca perf top: Fall back to cpu-clock-tick hrtimer sampling if no cycle counter available
On architectures/CPUs without PMU support but with perfcounters
enabled 'perf top' currently fails because it cannot create a
cycle based hw-perfcounter.

Fall back to the cpu-clock-tick sw-perfcounter in this case, which
is hrtimer based and will always work (as long as perfcounters
is enabled).
