PASN: Add functions to compute PTK, MIC and hash

Browse source 
1. Add a function to derive the PTK from a PMK and additional data.
2. Add a function to calculate the MIC for a PASN frames.
3. Add a function to compute the hash of an authentication frame body.

The above are built only in case that CONFIG_PASN is enabled at build
time.
