From: Hans Verkuil <hans.verkuil at cisco.com>

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.

Regards,

	Hans

Changes since v1:

- Move the dts change to meson-gx.dtsi since according to Neil it is
  valid for all meson-gx boards.
- Fix bad subject line of patch 1.
