drm/i915/selftests: exercise mmap migration

Browse source

Exercise each of the migration scenarios, verifying that the final
placement and buffer contents match our expectations.

v2(Thomas): Replace for_i915_gem_ww() block with simpler object_lock()

v3:
- For testing purposes allow forcing the io_size such that we can
  exercise the allocation + migration path on devices that don't have the
  small BAR limit.
