Some boards (amlogic) have two CEC controllers: the DesignWare controller
and their own CEC controller (meson ao-cec).

Since the CEC line is not hooked up to the DW controller we need a way
to disable that controller. This patch series adds the cec-disable
property for that purpose.

Neil, I have added cec-disable to meson-gxl-s905x-libretech-cc.dts
only, but I suspect it is probably valid for all meson-glx devices?
Should I move it to meson-gxl.dtsi?
