[SRU] [OEM-5.14] [PATCH 0/1] Fix spurious wakeup caused by Intel 7560 WWAN

[Kai-Heng Feng]

BugLink: https://bugs.launchpad.net/bugs/1956443

[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.
