Subject: drm: rcar-du: of: Include header to define prototypes
Git-commit: c18e9a098605abe5a1dc1c5dd9cfeda322ed36d8
Patch-mainline: v4.18-rc1
References: FATE#326289 FATE#326079 FATE#326049 FATE#322398 FATE#326166

The symbol 'rcar_du_of_init' is defined by the rcar_du_of module header,
but it is not included by the C implementation.

Include the header to correctly define the function prototypes.

Fixes the following warning:

linux/drivers/gpu/drm/rcar-du/rcar_du_of.c:319:13:
   warning: symbol 'rcar_du_of_init' was not declared. Should it be static?
    CC      drivers/gpu/drm/rcar-du/rcar_du_of.o
