Subject: [PATCH v2 13/18] ARM: dts: imx6q-apalis: Add adv7280 video input

From: Oleksandr Suvorov <oleksandr.suvorov@toradex.com>

The Apalis iMX6 modules allow connecting a parallel video input.
Add support for our ADV7280 video input module but have it disabled.
This allows to enable it in an overlay per the current system
configuration.

Changes in v2:
- Added "adv,force-bt656-4" property as suggested by Fabio.
  Note: in my PAL setup I didn't see any noticable change.
