drm/tilcdc: Remove tilcdc slave support for tda998x driver

Remove tilcdc slave support for tda998x driver. The tilcdc slave
support would conflicts with componentized use of tda998x.

Documentation/devicetree/bindings/drm/tilcdc/slave.txt

-Device-Tree bindings for tilcdc DRM encoder slave output driver
-
-Required properties:
- - compatible: value should be "ti,tilcdc,slave".
- - i2c: the phandle for the i2c device the encoder slave is connected to
-
-Recommended properties:
- - pinctrl-names, pinctrl-0: the pincontrol settings to configure
-   muxing properly for pins that connect to TFP410 device
-
-Example:
-
-	hdmi {
-		compatible = "ti,tilcdc,slave";
-		i2c = <&i2c0>;
-		pinctrl-names = "default";
-		pinctrl-0 = <&nxp_hdmi_bonelt_pins>;
-	};
