Work that completed in kernel 6.18 resulted in working suspend with DC
on old hardware. This series aims to backport it to 6.12 to have working
suspend there as well.

All commits were applied with git cherry-pick, the only changes being
adding upstream commit, and signing off.

Tested on AMD HD7750 with:
radeon.si_support=0 amdgpu.si_support=1 amdgpu.dc=1
on Arch Linux.

v2: add extra upstream fix.
