OPP: Introduce OPP bindings V2 and supporting code

Now that I have received an verbal Ack from Rob Herring (in a personal conversation) about the bindings, I am showing how the code looks like with these new bindings.

Some part is still now done:
- Interface for adding new detailed OPPs from platform code instead of DT
- Providing cpufreq helpers for the next OPPs
- Providing regulator helpers for the target/min/max ranges

Please provide feedback on how this looks like..
