The eye diagram (Host High-speed Signal Quality) tests are failed with 
the current settings. So design team asked to revert.

I thought of submitting it separately. But what-if only the first patch 
merged and second one didn't due to some issue, it will break the USB 
feature. So, I thought it would be better to keep it in single commit. 
Please let me know, I can send V2 with 2 patches with the merging 
strategy (both patches should go together to avoid the USB breakage) in 
cover letter.
