arm64: dts: freescale: Add dual-channel LVDS overlay for TQMa8MPxL
This adds an overlay for the supported LVDS display AUO G133HAN01. Configure the video PLL frequency to exactly match typical pixel clock of 141.200 MHz. Signed-off-by: Alexander Stein <alexander.stein@ew.tq-group.com> Signed-off-by: Shawn Guo <shawnguo@kernel.org>
