Subject: drm/i915: Select DEBUG_FS for our test suite
Git-commit: 1b2b659141cfa7c96c62c79516662a34ad112284
Patch-mainline: v4.16-rc1
References: FATE#326289 FATE#326079 FATE#326049 FATE#322398 FATE#326166

Ensure that we build our test kernels with DEBUG_FS enabled as many of
our igt tests require poking around debugfs/dri.

This should also fixup the kbuild complaint that we tried to select
SW_SYNC without meeting its dependencies.
