drm/amd/display: Introduce power module on Linux
[Why]
Other OS supported by DC uses the power module to manage panel power
features such as backlight and self-refresh. It contains enhancements
on top what amdgpu_dm is doing today that can benefit power.
[How]
Introduce the power module. It's currently not being used anywhere, a
future change will incorporate it into amdgpu_dm.
