[PATCH v3 7/7] arm64: dts: renesas: white-hawk: Add second mini-DP output support

[Tomi Valkeinen]

From: Geert Uytterhoeven <geert+rene...@glider.be>

Add support for the mini-DisplayPort connector on the White Hawk
BreakOut board.  This port is driven by a TI SN65DSI86 DSI to eDP
bridge, which in turn gets the pixel data from the second DSI channel on
the R-Car V4H SoC.  Note that this port is not present on the White Hawk
Single development board.
