Adjusts the GPU power limit, clocks, and the voltage curve -- using the `custom` profile in the driver.  This opens up further tweaking through the driver (currently manual).  see: [pp-dpm](https://docs.kernel.org/gpu/amdgpu/thermal.html#pp-dpm) |

 ## Notable variables
  - Power control: (float) multipliers to determine power _limits_ from board power _capability_
    - `power_max_default_multi`: Controls power for the generated `default` GPU profile.  Provided: `0.75` for 75% board power capability.
