kernel-rebase: Drop i915 and AMD drm changes
Specifically i915 changes are causing crashes in kernel-rebase.
Example:

Other crashes were seen as well. Trying to track down the problems as part
of the rebase is all but impossible. i915 / AMD related private changes
will have to be re-applied after the rebase is complete.
