Commit 36c0f8b32c4bd4f6 ("[media] vb2: replace void *alloc_ctxs by
struct device *alloc_devs") removed the vb2_dma_contig_init_ctx() and
vb2_dma_contig_cleanup_ctx() functions, and changed the prototype of
vb2_ops.queue_setup().

To fix this:
  - Update the signature of fdp1_queue_setup(),
  - Convert the FDP1 driver to use the new vb2_queue dev field, cfr.
    commit 53ddcc683faef8c7 ("[media] media/platform: convert drivers to
    use the new vb2_queue dev field").
