Subject: ath10k-ct: reduce memory consumption
ath10k uses a rather high number of buffers to communicate with the QCA
firmware. Especially the HTC (host-target-communication) and HTT
(host-target-transport) can take up a lot of memory when data is
transferred over a ath10k wifi link.
This problem was already worked around in commit cc189c0b7fa0 ("mac80211:
enable ath10k AHB support for QCA4019") for the ath10k driver from
mac80211. But this change was forgotton for the ath10k-ct driver.
