hacky solution to integrate AMDGPU power profile control in `tuned` with Ansible
## Notable variables
- ``: Accepts a float from (presumably) 0.0 to 1.0. Allows max GPU power consumption to be controlled. Default: `0.9` for 90%, roughly stock 3D peak.
- `card`: Sets the `card#` to use in the qualified sysfs path `/sys/class/drm/{{ card }}/device/pp_power_profile_mode`. Default: `card0`
- `base_profiles`: List of base tuned profiles to clone in the new AMDGPU profiles. Defaults:
- `desktop`
