sun4i-drm changes for 4.13

An unusually big pull request for this merge window, with three notable
features:
  - V3s display engine support. This is especially notable because it uses
    a different display engine used on the newer Allwinner SoCs (H3, A64
    and the likes) that will be quite easily supported now.
  - HDMI support for the old Allwinner SoCs. This is enabled only on the
    A10s for now, but should be really easy to extend to deal with A10, A20
    and A31
  - Preliminary work to deal with dual-pipeline SoCs (A10, A20, A31, H3,
    etc.). It currently ignores the second pipeline, but we can use the
    dual-pipelines bindings. This will be useful to enable the display
    pipeline while we work on the dual-pipeline.
