dmesg: HSW Desktop 3 response time.

HSW Desktop with the same eDP panel of Baytrail:
------------------------
Acquire initcall time:
1599.312 msecs             (Baytrail: 1613.640 msecs)
Acquire suspend time:
1018.271 msecs             (Baytrail: 841.988 msecs)
Acquire resume time:
576.649 msecs              (Baytrail: 10057.757 msecs) 


Using the same eDP panel to test the response time on HSW Desktop, the resume
time isn't that large even though we also have a bug to track it. Can you help
me to analyse the data and tell me what should I do. I append the dmesg on HSW
Desktop, and hope it's useful for you.
