Actually, on a closer look not even that: the ath9k LED support
in openwrt is quite different from upstream, and it just uses
gpio-led there, with a gpio provider in the driver for the
internal gpios.
We can probably just remove the gpiolib consumer side from
ath9k entirely then: it's not needed for the PCI devices
at all, and the SoC devices no longer use it upstream or
in openwrt.
