So something like 'serdes_refclk: clock-cmnrefclk' would seem to match the current
naming style of other K3 platforms (albeit except j7200).

80 is the index into the mmio region. So should it still have @ for the node
name?

Also this is how the rest of the K3 platforms reference the mux controller.

So something like 'wiz0_pll0_refclk: clk-refpll0'?
