[Impact]
The system wakes up during s2idle with Intel DG2 GPU.
It causes high power consumption during suspend.

[Fix]
Enable D3cold at s2idle.

[Test]
Tested on hardware, the system sleeps as long as expected,
the power consumption is lower.

[Where problems could occur]
It may break i915 driver.

It's a fix of regression in v6.1, no need for jammy and already in 6.5.
SRU for lunar and oem-6.1.
