[RFC][PATCH 00/10 v2] Add HDMI audio support for HiKey

[John Stultz]

This patch set is required for HDMI audio support on HiKey.

This version tries to address issues and adopt suggestions from
Mark Brown. I've split up the ASoC patches into i2s and codec
components, and done some major rework of those two patches.

The k3dma patches are mostly the same, with some minor tweaks
in the debug output suggested by Zhangfei.

I've also added draft dt bindings. Though I suspect they will
need more tweaks.

Again, the work is mostly that of Andy Green's, but I've taking
a swing at forward porting and cleaning it up where I saw fit.
So credit to Andy and blame to me. Apologies in advance, as I'm
not super familiar with either DMA or ASoC driver.

The one bit missing to have audio fully working is changes to the
adv7511 driver, but most of those changes are still out of tree, so
I'll submit those changes once they land.

Feedback would be very much appreicated!

thanks
