Revert "wcn36xx: Disable bmps when encryption is disabled" This reverts commit c6522a5076e1a65877c51cfee313a74ef61cabf8. Testing on tip-of-tree shows that this is working now. Revert this and re-enable BMPS for Open APs.

wcn36xx: Treat repeated BMPS entry fail as connection loss On an open AP when you pull the plug on the AP, if we are not already in BMPS mode then the firmware will not generate a disconnection event. Instead we need to monitor for failure to enter BMPS and treat a string of failures as connection loss. Secure AP connections don't appear to demonstrate this behavior so the work-around is limited to open APs only.

wcn36xx: Advertise beacon filtering support in bmps In bmps mode, beacons are filtered, and firmware is in charge of monitoring the beacons and report changes or loss. mac80211 must be advertised about such change to prevent it's internal timer based beacon monitor to report beacon loss. Fix that by setting/clearing the IEEE80211_VIF_BEACON_FILTER vif flag on bmps entry/exit.

wcn36xx: Disable bmps when encryption is disabled For whatever reason, when connected to an open/no-security BSS, the wcn36xx controller in bmps mode does not forward 'wake-up' beacons despite AP sends DTIM with station AID. Meaning that AP is not able to wakeup the station and needs to wait for the station to wakeup by its own (TX data, keep alive pkt...), causing serious latency issues and unexpected deauth. When connected to AP with encryption enabled, this issue does not occur. So a simple workaround is to only enable bmps support in that case. Ideally, it should be propertly fixed to allow bmps support with open BSS, whatever the issue is at driver or firmware level. Tested on wcn3620 and wcn3680.

wcn36xx: Fix dynamic power saving Since driver does not report hardware dynamic power saving cap, this is up to the mac80211 to manage power saving timeout and state machine, using the ieee80211 config callback to report PS changes. This patch enables/disables PS mode according to the new configuration. Remove old behaviour enabling PS mode in a static way, this make the device unusable when power save is enabled since device is forced to PS regardless RX/TX traffic.
