Subject: [PATCH] wcn36xx: Fix HT40 capability for 2Ghz band
Git-commit: 960ae77f25631bbe4e3aafefe209b52e044baf31
References: git-fixes
Patch-mainline: v5.16-rc1
All wcn36xx controllers are supposed to support HT40 (and SGI40),
This doubles the maximum bitrate/throughput with compatible APs.
Tested with wcn3620 & wcn3680B.
