That's not possible. The frontend drivers just take some register reading
and mangle it into a 16-bit value where "higher means better". To have a
percentage, the reading would have to be linearized and normalized in a
hardware-specific way.

To implement percentage readings, you would have to change _all_ frontend
modules and figure out the hardware-specific ranges, and you would probably
need to have all hardware available for analysis to do this.

The lack of any definitions of the range and of the signal readings is an
unfortunate oversight, which I don't think can be fixed anytime soon.
