Are you sure this is necessary? If the clk controller follows
a logical structure, it's usually easier to identify individual
clks by the way the hardware is laid out.

Unlike the DT compatible strings, these #defines don't have
to be specific to a particular SoC, you could just reuse them
for a family of chips even if they each use a slightly different
subset. Maybe name them "ADSP_CLK_*" or "ADSP_SC5XX_CLK_*"?

This should not be part of the binding, in particular you
probably want to be able to extend this in order to support
additional chips.
