wifi: rtw89: add WoWLAN function support
WoWLAN is a feature which allows devices to be woken up from suspend
state through WLAN events.
When user enables WoWLAN feature and then let the device enter suspend
state, WoWLAN firmware will be loaded by the driver and periodically
monitors WiFi packets. Power consumption of WiFi chip will be reduced
in this state.
We now implement WoWLAN function in rtw8852ae and rtw8852ce chip.
Currently supported WLAN events include receiving magic packet,
rekey packet and deauth packet, and disconnecting from AP.
