From: Miles Hu <milehu@codeaurora.org>

This patch adds ath11k support for setting fixed HE rate/gi/ltf values that
we are now able to send to the kernel using nl80211. The added code is
reusing parts of the existing code path already used for HT/VHT. The new
helpers are symmetric to how we do it for HT/VHT.
