Update the bindings documenting the new hdmi phandle and
update exynos4.dtsi accordingly. This phandle is needed by the
s5p-cec driver to initialize the HPD notifier framework.

Tested with my Odroid U3.

The bindings description can be a separate patch (often welcomed) but
does not have to. It may be squashed with driver changes. But not with
DTS changes because DTS should go through samsung-soc tree (alone). The
bindings description usually go through subsystem maintainer.

When sending the bindings description, please Cc at least
devicetree@vger.kernel.org as mentioned by get_maintainers. It is
welcomed to Cc also DT maintainers (Rob & Mark) although with simple
bindings extension I think it is not a necessity.

Anyway please split this and name the subject (git log --oneline
arch/arm/boot/dts/exynos*: "ARM: dts: exynos: Foo Bar").

Best regards,
Krzysztof
