rtw89: 8852a: update HW setting on BB
Sometimes, BB might encounter RX problem on OFDM 6M. It's not quite
easy to happen, but if it happens, we will keep getting stuck on RX.
And, since we cannot properly receive layer 2 ACK, it also casues TX
problem, e.g. constantly retrying TX. Eventually, after some time, we
would get disconnected due to abnormal behavior.
Update break setting and phy status parsing time to make BB get out
of stuck state faster.
