Stop using C99 types in XE rather use kernel types

@demarchi pointed this out:

$ git grep uint[836] -- drivers/gpu/drm/xe | wc -l
186

Hmm, but lots of other drivers in the DRM subsystem use C99 types... Either way we should pick either C99 types or kernel types and use one or the other.

mentioned in merge request !70 (merged)

"lots of other drivers" have issues in coding style. See git log --grep "prefer kernel type" for some commits changing them.

This is fixed in !69 (merged)

Moved this single fix to !72 (merged)

Fix is merged, closing.
