Add Class D audio amplifier node to sama5d2 description. The binding
documentation is already accepted and included as
Documentation/devicetree/bindings/sound/atmel-classd.txt.

Hi,
Note that this node needs the audio PLL clock which is not submitted yet. So,
this series can't be applied right now: we have to wait for the audio PLL
driver and binding to be accepted and included first.
I send it right now so that it's not forgotten and easyer to track. Moreover,
the binding won't certainly change.
Bye,
