Introduce a gem migrate interface, add a selftest and use it for display fb pinning and dma-buf mapping. This series should make accelerated desktop work on DG1 with DG1-enabled OpenGL. v2: - Address review comments by Matthew Auld on patch 1/5. More details on the patch commit message. - Address a dma-buf locking issue pointed out by Michael Ruhl, and add a selftest to catch that issue moving forward. - Rebase the dma-buf migration patch on the above-mentioned fix.
