ARM: dts: sun8i: a83t: Add device node for CSI (Camera Sensor Interface)
The A83T SoC has a camera sensor interface (known as CSI in Allwinner lingo), which is similar to the one found on the A64 and H3. The only difference seems to be that support of MIPI CSI through a connected MIPI CSI-2 bridge. Add a device node for it, and pinctrl nodes for the commonly used MCLK and 8-bit parallel interface. The property /omit-if-no-ref/ is added to the pinctrl nodes to keep the device tree blob size down if they are unused.
