[RESEND][PATCH 0/2 v4] Audio support for adv7511 hdmi bridge

[John Stultz]

Just wanted to resend the adv7511 hdmi bridge audio support for
review and consideration for merging.

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. 

As suggested, I do intend to rework the dts changes (not submitted
here) to use the of graph simple-card, instead of the simple-card
method I currently use, but I don't believe that that change would
effect these patches.

I'd really appreciate any thoughts or feedback.

thanks
