Subject: wcn36xx: Fix HT40 capability for 2Ghz band
From: Loic Poulain <loic.poulain@xxxxxxxxxx>
commit 960ae77f25631bbe4e3aafefe209b52e044baf31 upstream.
All wcn36xx controllers are supposed to support HT40 (and SGI40),
This doubles the maximum bitrate/throughput with compatible APs.
Tested with wcn3620 & wcn3680B.
