Subject: drm/amd/powerplay: update how to use metrics table on Navi10
Git-commit: cf24dd2780c3b58669904a78fe8b549c69282102
Patch-mainline: v5.9-rc1
References: jsc#SLE-12680, jsc#SLE-12880, jsc#SLE-12882, jsc#SLE-12883, jsc#SLE-13496, jsc#SLE-15322
Retrieve only those data interested instead of the whole table.
