We would like to switch from benchmark trained profiles to profiles
collected in the field. An unified profile from Silvermont machines will
be used in the beginning.

We would like to put this change in the branch. 
We were waiting for data from 66 stable and it took a while so we missed the 68 branch point. 
But this change is pretty safe and has been tested on ToT without any issues.
It is just a change on the profiles. No other functional changes.

Your change meets the bar and is auto-approved for M68. Please go ahead and merge the CL to branch 3440 manually. Please contact milestone owner if you have questions.
