Is this really a hardware description though ?

Its really more of a logical/functional description. It tells the 
runtime what todo, not what the hardware is.

You could also have a list of quirks in ath12k for this or have a 
user-space utility look for the appropriate platform device string name 
and disable rfkill.

I think this logic belongs in drivers/net/wireless/ath/ath12k/ 
triggering on a compat string.

Should be achievable.
