Subject: drm/amd/powerplay: correct the value retrieved through GPU_LOAD
Git-commit: a0250689cbb5a8e32f816b3c4778920ce7c44d91
Patch-mainline: v5.6-rc1
References: jsc#SLE-12680, jsc#SLE-12880, jsc#SLE-12882, jsc#SLE-12883, jsc#SLE-13496, jsc#SLE-15322
sensor interface
the unit of variable AverageGfxActivity defined in smu12 metrics
struct is centi, so the retrieved value should be divided by 100 before
return.
