wifi: rtw88: 8821a: Regularly ask for BT info updates

Browse source

The RTL8821AU firmware sends C2H_BT_INFO by itself when bluetooth
headphones are connected, but not when they are disconnected. This leads
to the coexistence code still using the A2DP algorithm long after the
headphones are disconnected, which means the wifi speeds are much lower
than they should be. Work around this by asking for updates every two
seconds if the chip is RTL8821AU.
