cfg80211: Advertise maximum associated STAs in AP mode
This allows drivers to advertise the maximum number of associated stations they support in AP mode (including P2P GO). User space applications can use this for cleaner way of handling the limit (e.g., hostapd rejecting IEEE 802.11 authentication without manual configuration of the limit) or to figure out what type of use cases can be executed with multiple devices before trying and failing.
