power_Resume: inaccurate estimate of firmware_ec resume time

Project Member Reported by jcliang@chromium.org, Apr 15 2016 
Version: any version after chromeos release 8142.0.0
OS: Chrome OS

What steps will reproduce the problem?
(1) find a board with proven resume time less than 1 second
(2) run power_Resume
(3) check the seconds_system_resume_firmware_ec field

What is the expected output?

seconds_system_resume_firmware_ec should be small

What do you see instead?

seconds_system_resume_firmware_ec is greater than 1 second

Please use labels and text to provide additional information.

I... don't know what I have to do with this metric. :-)

It looks like it's in power_suspend.py. Julius, I think that you wrote this, right?

I think this is a known issue that Derek is already working on somewhere.

This also does this while playing .swf media playback on the fly as well, if the system locks itself for long periods of time, the resume process will take as long enough itself also.
