[Intel-gfx] [PATCH i-g-t] i915/gem_mmap_gtt: Skip if we have no aperture and no mmap_gtt

[Chris Wilson]

If the device does not expose an aperture for indirect access with
detiling functionality, the kernel rejects an attempt to create such a
mapping with -ENODEV. If the ioctl is not supported, we can skip all of
our mmap_gtt specific tests.
