Revert "drm/i915: Don't use BAR mappings for ring buffers with LLC"

Browse source 
This reverts commit 4eb6789f9177a5fdb90e1b7cdd4b069d1fb9ce45 which is
commit 85636167e3 upstream.

It has been reported to cause problems on Alpine Linux and Manjaro Linux
5.15-based releases, so revert it for now until it can be sorted out.
