Subject: [PATCH v2 09/19] ARM: dts: imx6-sabreauto: add the ADV7180 video decoder

Enables the ADV7180 decoder sensor. The ADV7180 connects to the
parallel-bus mux input on ipu1_csi0_mux.

On the sabreauto, two analog video inputs are routed to the ADV7180,
composite on Ain1, and composite on Ain3. Those inputs are defined
via inputs and input-names under the ADV7180 node. The ADV7180 power
pin is via max7310_b port expander.
