Patch 6 documents qcom,hawi-lpass-rx-macro with `clock-names` containing 
`lpr` instead of `macro`:

     clock-names = "mclk", "lpr", "dcodec", "fsgen"

https://lore.kernel.org/all/20260922095522.193FC1F00893@smtp.kernel.org/

However, this patch only adds the compatible string and reuses the 
existing RX probe path, which still requests the clock as `macro`:

     rx->macro = devm_clk_get_optional(dev, "macro");

I do not see any Hawi-specific handling which requests or enables `lpr`.
Should the driver be updated to request `lpr` for the Hawi compatible, 
or should the binding continue to use `macro` if this is the same clock 
from the driver's point of view?
