drm/amd: Introduce `AMDGPU_PP_SENSOR_GPU_INPUT_POWER`

2023-08-15T22:08:29+00:00

Some GPUs have been overloading average power values and input power values. To disambiguate these, introduce a new `AMDGPU_PP_SENSOR_GPU_INPUT_POWER` and the GPUs that share input power update to use this instead of average power.
