[PATCH RESEND] gpu: drm: rcar-du: rcar_du_drv: don't open code of_device_get_match_data()

[Wolfram Sang]

This change will also make Coverity happy by avoiding a theoretical NULL
pointer dereference; yet another reason is to use the above helper function
to tighten the code and make it more readable.

Found this in one of my old branches. Plain resend, only ack from Geert added.
