v2:
Rewrote commit messages to explain why the changes are necessary & provide
explanations of jargon.
Changed author of first commit to myself and removed Bryan's Signed-off-by:
due to my changes. Added Bryan's Reviewed-by: on second patch.
v1:
Think Bryan's commit was accidentally lost during upstreaming of his original
WCN3680 support patches, so I've included it here.
Omitted Fixes: tag as this was a regression from downstream prima, but not a
regression from previous versions of wcn36xx.

2.25.1
The official feature-complete WCN3680B driver (known as prima, open source
but not upstream) sends this feature bit.
As we wish to support the antenna diversity feature in upstream, we need
to set this bit as well.

2.25.1
The official feature-complete WCN3680B driver (known as prima, open source
but not upstream) supports channels 136 and 144.
However, these channels are missing in upstream. Add them here to get
closer to feature parity with prima.
