Not updating the driver state in park will not negatively impact

If i understand it correctly (how its calculated), no. not capturing on every
park/unpark
does not mean less accuracy. Umesh mentioned to verify that with
igt@perf-pmu@accuracy
tests
Okay you moved it from guc_update_engine_gt_clks to
intel_guc_busyness_park to work around the loss of accuracy. I almost
missed it since patch itself has not changelog. Works for me if Umesh
approves it is correct.
