Extra blank line accidentally being added here.

Also I would probably make the shifting of the shared_lrclk
handling a different patch as that is a bug fix and shouldn't
really be tided into a patch adding DT bindings.

As pointed out this will need a corresponding DT documentaion
patch, but apart from those things looks good to me.
