Bug Description
[Impact]
Spurious wakeup from s2idle caused by Intel 7560 WWAN device.
[Fix]
Keep the device at D0 to prevent the unwanted wakeup. Since PCIe ASPM is
enabled, the power consumption impact is minimal.
[Test]
No more spurious wakeup on s2idle.
[Where problems could occur]
If the device somehow requires to be power-cycled via D3, this may break
the assumption.
