perf/x86/amd/uncore: Add parameter to configure hrtimer

Browse source

Introduce a module parameter for configuring the hrtimer duration in
milliseconds. The default duration is 60000 milliseconds and the intent
is to allow users to customize it to suit jitter tolerances. It should
be noted that a longer duration will reduce jitter but affect accuracy
if the programmed events cause the counters to overflow multiple times
in a single interval.
