drm/amdgpu/smu_v11_0: Correct behavior of restoring default tables (v2)
Previously, the syfs functionality for restoring the default powerplay
table was sourcing it's information from the currently-staged powerplay
table.
This patch adds a step to cache the first overdrive table that we see on
boot, so that it can be used later to "restore" the powerplay table
v2: sqaush my original with Matt's fix
