Subject: [PATCH 4072/4131] Revert "drm/amd/powerply: fix power reading on
Fiji"
we don't have limit of [50ms, 4sec] sampling period.
smu calculate average gpu power in real time.
we can read average gpu power through smu message or
read special register.
This reverts commit 462d8dcc9fec0d89f1ff6a1f93f1d4f670878c71.
