flo: Initial tuning of device tunables

- Tune interactive governor based on my work on Moto X.
- Tune cpu-boost driver based on my work on Moto X.
- Disable FSync and software CRCs as they don't
appear to have much adverse effects as tested on Moto X.
- Set GPU to the custom conservative GPU governor as
tested on Moto X.
