[PULL] drm-xe-next

Hi Dave and Sima,

Second drm-xe-next pull request for the 6.12 cycle.

Several fixes here that are also going through drm-xe-fixes. Most of the
other changes are the missing bits for Xe2 (LNL and BMG) and general
refactors.

The only UAPI change is actually a fix for building with gcc 5.

I left some commits out since they were too fresh and I didn't have core
CI results for them. Plan is to send the final pull request for 6.12
next week with those commits.

thanks
Lucas De Marchi
