drm/i915/gem: Migrate to system at dma-buf attach time (v7)
Until we support p2p dma or as a complement to that, migrate data
to system memory at dma-buf attach time if possible.
v2:
- Rebase on dynamic exporter. Update the igt_dmabuf_import_same_driver
selftest to migrate if we are LMEM capable.
v3:
- Migrate also in the pin() callback.
v4:
- Migrate in attach
v5: (jason)
- Lock around the migration
v6: (jason)
- Move the can_migrate check outside the lock
- Rework the selftests to test more migration conditions. In
particular, SMEM, LMEM, and LMEM+SMEM are all checked.
v7: (mauld)
- Misc style nits
