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'?

Sorry for the confusion, I meant clock-<abc>. DT specification says all
clock nodes should follow above naming convention

@addr can only be used with nodes that have reg property. And since
there is no reg here -> would follow mux-controller-<abc> convention.

We need to fix other dtsi files to drop @addr part as they are now
falling make dtbs_check
