Fix device utilization reporting breakage.

Device utilization computation converted the values to hz, assuming the
device is 100 HZ, which is not necessarily the case. This change converts
everything to ms. Device utilization computation now works on marlin (P).

Test: Test app-launcher and make sure device util% reported is correct.
