[LEDE-DEV] [PATCH] ath10k: Re-enable intermediate softqueues for all devices

[Toke Høiland-Jørgensen]

The upstream ath10k driver disables the intermediate softqueues for some
devices. This patch reverts that behaviour and always enables the
softqueues (and associated bufferbloat fixes). We have had reports of people
running this with good results:
https://lists.bufferbloat.net/pipermail/make-wifi-fast/2017-September/001497.html

This also refreshes mac80211 patches.
