[Why]
Before this patchset, navi10 users could not utilize the overdrive
functionality. This prevented them from overclocking, overvolting, or
undervolting their cards.
[How]
Similar to the vega20 implementation, add the pp_od_clk_voltage
interface to the navi10 powerplay table.
[Possible Alternatives]
This could also be done more generically in smu_v11_0 code, but would
require more significant changes to the vega20 code, and feature-gating
based on chip capabilities in the smu to disable overdrive for arcterus.
I chose this path so as not to completely refactor the vega20 side of
things, and introduce SMU code which would not play nicely with new
ASICs.

Subject: [PATCH 2/3] drm/amdgpu/navi10: implement GFXCLK_CURVE overdrive
To: amd-gfx@lists.freedesktop.org
[Why]
Before this patch, there was no way to set the gfxclk voltage curve in
the overdrive settings for navi10 through pp_od_clk_voltage
[How]
Add the required implementation to navi10's ppt dpm table editing
implementation, similar to the vega20 implementation and interface.
