Adds DPU(Display Processor Unit) support for the Unisoc's display
subsystem.
It's support multi planes, scaler, rotation, PQ(Picture Quality) and more.

  - Use drm_xxx to replace all DRM_XXX.
  - Use kzalloc to replace devm_kzalloc for sprd_dpu structure init.

  - Remove dpu_layer stuff layer and commit layers by aotmic_update

v4:
  - Use drmm_helpers to allocate crtc and planes.
  - Move rotation enum definitions to crtc layer reg bitfields.
  - Move allocate crtc and planes to bind function.

v5:
  - Fix the checkpatch warnings.
  - Use mode_set_nofb instead of mode_valid callback.
  - Follow the OF-Graph bindings, use of_graph_get_port_by_id
    instead of of_parse_phandle.
  - Use zpos to represent the layer position.
  - Rebase to last drm misc branch.

v6:
  - Disable and clear interrupts before register dpu IRQ
  - Init dpi config used by crtc_state->adjusted_mode on mode_set_nofb
  - Remove enable_irq and disable_irq function call.
  - Remove drm_format_info function call.
