drm/amd/pm: Fix sienna cichlid incorrect OD volage after resume
Always setup overdrive tables after resume. Preserve only some
user-defined settings in user_overdrive_table if they're set.
Copy restored user_overdrive_table into od_table to get correct
values.
On cold boot, BTC was triggered and GfxVfCurve was calibrated. We
got VfCurve settings (a). On resuming back, BTC will be triggered
again and GfxVfCurve will be recalibrated. VfCurve settings (b)
got may be different from those of cold boot. So if we reuse
those VfCurve settings (a) got on cold boot on suspend, we can
run into discrepencies.
