wifi: iwlwifi: mvm: implement PHC clock adjustments

Browse source

Implement the following PHC operations:
1. adjtime - for adding an offset to the PHC clock time.
2. adjfine - for adjusting the PHC clock frequency.
3. gettime64 - for getting the PHC clock time. This function returns
   the time as adjusted by adjtime and adjfine.

The adjusted time will also be used for time sync frames timestamping.
