+Common bindings for HDMI CEC adapters

+- hdmi-phandle: phandle to the HDMI controller.
For a common property I would rather make it "hdmi-controller", this
"-phandle" part feels like appending "_pointer" to variable names in C code.
But since you are just rearranging existing documentation and Rob agrees with
that I have no objections.
+- needs-hpd: if present the CEC support is only available when the HPD
+ is high. Some boards only let the CEC pin through if the HPD is high,
+ for example if there is a level converter that uses the HPD to power
+ up or down.
