[PATCH v7 10/18] media: vsp1: drm: Extend frame completion API to the DU driver

[Laurent Pinchart <laurent.pinchart+renesas@xxxxxxxxxxxxxxxx>]

The VSP1 driver will need to pass extra flags to the DU through the
frame completion API. Replace the completed bool flag by a bitmask to
support this.

Changes since v6:

- Add a comment to keep VSP1_DU_STATUS_* and VSP1_DL_FRAME_END_* in sync
