Subject: [PATCH v9 2/5] ARM: dts: stm32: add DSI support on stm32f769

Add support for MIPI DSI Host controller. Since MIPI DSI is not
available on stm32f746, the patch adds the "stm32f769.dtsi" file
containing the dsi node inside.

Signed-off-by: Dario Binacchi <dario.binacchi@...rulasolutions.com>
