[PATCH v12] ath10k: add LED and GPIO controlling support for various chipsets

in our case here it can coexist and will not have a negative effect 
since the led will still run. (except if you reconfigure the gpio to input)
for sure it makes no sense.
but however i can block the gpio for beeing reused if the led driver 
took it. this has been made in ath9k for instance.
in ath10k i did not do it, since there is no technical requirement for it.
but that might not be the case for all gpio controllers, so there is no 
generic answer. for ath10k. harmless
