Because optimizing the power consumption of t7XX,
change auto suspend time to 5000.

The Tests uses a script to loop through the power_state
of t7XX.
(for example: /sys/bus/pci/devices/0000\:72\:00.0/power_state)

* If Auto suspend is 20 seconds,
  test script show power_state have 0~5% of the time was in D3 state
  when host don't have data packet transmission.

* Changed auto suspend time to 5 seconds,
  test script show power_state have 50%~80% of the time was in D3 state
  when host don't have data packet transmission.
