The quirks apply to the devices, and are in the same format as what's
offered by the kernel when the firmware provides it, so it's not iio-
sensor-proxy specific in any way. If we were to replace iio-sensor-
proxy, we'd still use this metadata.

I'll send a patch in as soon as I've done testing on a machine that
does need this quirking.
