USB keyboard/mouse wake up from S3

[Shichun.Ma at dell.com]

Hi HPS,
Sorry, but I just have Intel SOC which only has XHCI integrated, 
I just tested with  Intel's Gemini Lake SOC, and I can further test it with DELL OptiPlex later.
I agree with your idea that preserves old behavior by default.

Thanks & Regards,

Also I want you to add a sysctl, hw.usb.no_wakeup, which if set,
preserves the old behaviour.

Thank you!
