Audio support for adv7511 hdmi bridge

This is another swing at getting the adv7511 hdmi bridge
audio support reviewed.

I've taken the core audio work done by Lars-Peter Clausen, and
adapted by Srinivas Kandagatla and Archit Taneja, and tried to
rework it to use the hdmi-codec sound driver.

This patchset, along with the i2s driver and dts changes allows
HDMI audio to work on the HiKey board.

I'd really appreciate any thoughts or feedback.

New in v3:
* Dropped unnecessary first patch
* Made a few clenaups suggested by Laurent
* Made audio a config time option, as suggested by Laurent
* Folded in Andy Green's audio packet initialization patch

thanks
