tests: Introduce i915 directory
We can already move all the tests with distinct prefixes: gem_, gen3_ and i915_. pm_ and drv_ tests will follow in batches, so we can do the adjustments in the reporting/filtering layer of the CI system. v2: Fix test-list.txt generation with meson v3: Fix docs build (Petri) Cc: Chris Wilson <chris@chris-wilson.co.uk> Cc: Petri Latvala <petri.latvala@intel.com> Cc: Martin Peres <martin.peres@linux.intel.com> Signed-off-by: Arkadiusz Hiler <arkadiusz.hiler@intel.com> Reviewed-by: Petri Latvala <petri.latvala@intel.com> Tested-by: Petri Latvala <petri.latvala@intel.com> Acked-by: Daniel Vetter <daniel.vetter@ffwll.ch> Acked-by: Chris Wilson <chris@chris-wilson.co.uk>
