Test and validate the behavior of a timer driver. Takes a number of absolute timer cycle samples of a periodic timer then calculates statistical mean, variance, stddev along with total drift over the entire test time. Ensures standard deviation and drift are within a given configurable bound. Signed-off-by: Tom Burdick <thomas.burdick@intel.com>
