[PATCH] ASoC: ADAU7118: add bindings for managing pins drive strength

[Sa, Nuno]

Hi Dylan,

Thanks for your patch. It looks good to me. I just have a small
remark in the bindings. Also, I don't think that both bindinds and
driver code should be on the same patch. You separate this
into 2 patches...

It would be nice to state here what's the meaning of 3,2,1,0...
