[cip-dev] [PATCH 4.19.y-cip 12/35] drm: rcar-du: Add R8A774B1 support

[prabhakar.mahadev-lad.rj@bp.renesas.com (Lad Prabhakar)]

From: Biju Das <biju.das@bp.renesas.com>

commit 47968ea96af335b56a0db6c305146e720363558c upstream.

Add support for the R8A774B1 DU (which is very similar to the R8A77965 DU
except that it lacks TCON and CMM); it has one RGB output, one LVDS output
and one HDMI output.
