[PATCH v3 06/20] ASoC: dt-bindings: replace q6afe-clk with q6dsp audio clk bindings

[Srinivas Kandagatla]

DSP Audio clock bindings have been documented with DSP services bindings
which makes it difficult to reuse them, so pull them out in to a dedicated
bindings.
Also as part of this change convert them into yaml format.

q6afe-clocks were part of q6afe bindings which are deleted in previous patch, this
patch just adds replacement bindings for clocks in yaml format.
