CARL9170_LEDS selects MAC80211_LEDS even though its kconfig
dependencies are not met. This happens because 'select' does not follow
any Kconfig dependency chains.
Fix this by making CARL9170_LEDS depend on MAC80211_LEDS, where
the latter supplies any needed dependencies on LEDS_CLASS.
Ok, this is not what I was expecting... I though you would just
add a "depends on / imply MAC80211_LEDS" on your v2. (this was
based on the assumption of what mac80211, ath9k/_htc and mt76
solutions of the same problem looked like).
But since (I assuming here) this patch passed the build-bots
testing with flying colors in the different config permutations.

Say Y, unless you need the LEDs for firmware debugging.
