Fix issue where USB ports not powered after suspend on newer machines
 
SRU Justification:
Recent Lenovo Thinkpads & other newer machines have begun to depend on
the OS to power on the USB controller after supsend wakeup. This is
apparently apart of the acpi specification, though before now the bios
has done this job. Fix is upstream & in stable branch of 2.6.33.

Fix:

Test Cases:
Wake up from suspend and usb ports are powered and usable.
