ARM: dts: imx6qdl-apalis: add GPIO I2C node for DDC

Currently, the DDC signals are controlled by the DWC HDMI I2C
master to be used for HDMI (DVI on the Apalis Evaluation Board).
However, the Apalis Evaluation board also allows to route the Apalis
DDC I2C to the LVDS or the VGA connector. By default, the signal
is routed to DVI (HDMI), and therefor the current default settings
are sensible.

To ease customization and to prepare for carrier boards with other
needs, add a GPIO I2C DDC node.

E.g. to reroute the Apalis DDC to the VGA connector on the Apalis
Evaluation Board, the following changes can be used:

vga {
	...
	ddc-i2c-bus = <&i2cddc>;
};

&hdmi {
	/delete-property/ pinctrl-0;
};

&i2cddc {
	status = "okay";
};
