OSP Framework - Driver model - documentation

[pkhade]

This would be needed by open source developers or customers when they'd like to do some ammends.

1. Requirement specification for OSP Daemon (includes functional, platform, device requirements)
2. Design spec that describes so called Driver model.

Specifically, make sure your design also mentions -

1. How this driver model is scalable if input or output driver IPC is not based on FS
2. How this driver model factors in algorithms (*this is close to the requirement mentioned in point 1)
