Subject: [PATCH] qtnfmac: update channel switch command to support 6GHz band
Git-commit: 5edadc5a3f1179b3e4db895d6a941e3d257eaa0c
Patch-mainline: v5.7-rc1
References: jsc#SLE-13430, bsc#1176741

With an addition of 6GHz band support, channel number can no longer be
used to uniquely identify a specific channel. Modify channel switch
command to use chandef data.
