[v2022 <- v2023] backport: d/patches: Fix kernel WARN on exit

Import patches from upstream to cleanup the exit sequence. The first 2 patches fix a kernel WARN message that is happening because plymouth is requestion CRTC info from the DRM driver after the DRM engine has already been turned off.

The last 2 patches ensure a clean exit on SIGTERM so that the screen doesn't flicker or show the console at the very end, especially with the i915 driver.

Fixes: infrastructure/apertis-issues#319 (closed)

This is a backport of !7 (merged) https://phabricator.apertis.org/T9698
