From: Mikhail Karpenko <mkarpenko@xxxxxxxxxxxxx>
Add support for 11ax features: TWT responder and spatial reuse.
Add separate structure for spatial reuse parameters and pass this
structure to firmware along with other parameters in start_ap
command. Pass TWT responder value to firmware. Bump qlink
protocol version.
