Given that this is present in all the "linux-libre" packages
(e.g. without arm-generic or arm64-generic ...), I think it makes sense
to add this to %default-extra-linux-options.

*Untested* patch attached.

I did at one point try to enable this on arm-generic and it required
additional features I couldn't track down... and at some point this was
enabled on arm64-generic (I tested on "pinebook" with arm64-generic a
while back).

live well,
