ARM: dts: rockchip: Add unwedge pinctrl entries for dw_hdmi on rk3288
This adds the "unwedge" pinctrl entries introduced by a recent dw_hdmi
change that can unwedge the dw_hdmi i2c bus in some cases. It's
expected that any boards using this would add:
pinctrl-names = "default", "unwedge";
pinctrl-0 = <&hdmi_ddc>;
pinctrl-1 = <&hdmi_ddc_unwedge>;
Note that this isn't added by default because some boards may choose
to mux i2c5 for their DDC bus (if that is more tested for them).
