drm/i915/lmem: Bypass aperture when lmem is available

Browse source

In the scenario where local memory is available, we have
rely on CPU access via lmem directly instead of aperture.

v2:
gmch is only relevant for much older hw, therefore we can drop the
has_aperture check since it should always be present on such platforms.
