OpenWrt: mac80211: add back ath10k_pci memory hacks
These hacks have been removed in OpenWrt commit 1e27befe63ff ("mac80211: remove ath10k_pci memory hacks"). However, since we still use mainline ath10k, we will need them. Signed-off-by: Adrian Schmutzler <freifunk@adrianschmutzler.de> Reviewed-by: Fabian Bläse <fabian@blaese.de>
