tests/pm_rc6_residency: Measure the sleep duration
The code is confused about the units of CODE_TIME. The comment
says 50 microsseconds, but the actual code makes it 50
milliseconds. Avoid the whole mess by measuring the sleep
duration ourselves. Since the time measurement is taken around
the whole operation it obviously includes a bit of extra, but
at least it's much less than the fixed 50 ms.
For instance on one VLV board I now get something like this:
- Residency in rc6 or deeper state: 3002 ms (ratio to expected duration: 0.98)
+ Residency in rc6 or deeper state: 3001 ms (sleep duration 3003 ms) (ratio to expected duration: 1.00)
so the reported ratio is now much closer to reality.
