Yet another pass on adding audio support to the adv7511 hdmi
bridge.

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 v4:
* Kconfig tweaks suggested by Lars-Peter Clausen

thanks
