[PATCH] drm: rcar-du: writeback: include interface header

[PATCH] drm: rcar-du: writeback: include interface header

[Kieran Bingham]

The new writeback feature is exports functions so that they can
integrate into the rcar_du_kms module.

The interface functions are defined in the rcar_du_writeback header, but
it is not included in the object file itself leading to compiler
warnings for missing prototypes.

Include the header as appropriate.

Good catch. I'll fix it in my branch.
