Subject: [PATCH 14/14] arm64: dts: freescale: Add the BOE av123z7m-n17
 variant of the Moduline Display

From: Maud Spierings <maudspierings@...ontroll.com>

Add the BOE av123z7m-n17 variant of the Moduline Display, this variant
comes with a 12.3" 1920x720 display.

Signed-off-by: Maud Spierings <maudspierings@...ontroll.com>
