wlan: Support SAP Auth Offload feature
For SAP Auth offload, station assoc and disassoc will happen
in firmware.
As soon driver is in waked up state, firmware
will send Assoc or disassoc indication to host.
In case of ADD STA indication, driver will parse all caps
of connected client and will register this client to TL and HDD.
In case of DEL STA indication, driver will remove entry for
this station and will start cleanup.
