Subject: [PATCH v2] arm64: dts: renesas: r8a77995-draak: Enable DU

From: Kieran Bingham <kieran.bingham+renesas@...asonboard.com>

Enable the DU, providing only the VGA output for now.

Just a v2 update to fix the PFC name, and collect Laurent's RB tag.  The
remainder of the series will likely be postponed due to dependencies on LVDS
changes etc.

v2:
 - Update du_dot_clk_0 name to match Ulrich's PFC configuration.
