6d62269283 rtlwifi: btcoexist: Fix antenna selection code 
In commit 87d8a9f352 ("rtlwifi: btcoex: call bind to setup btcoex"),
the code turns on a call to exhalbtc_bind_bt_coex_withadapter(). This
routine contains a bug that causes incorrect antenna selection for those
HP laptops with only one antenna and an incorrectly programmed EFUSE.
These boxes are the ones that need the ant_sel module parameter.

a33fcba6ec rtlwifi: btcoexist: Fix breakage of ant_sel for rtl8723be 
In commit bcd37f4a08 ("rtlwifi: btcoex: 23b 2ant: let bt transmit when
hw initialisation done"), there is an additional error when the module
parameter ant_sel is used to select the auxilary antenna. The error is
that the antenna selection is not checked when writing the antenna
selection register.

0d4ae14226 rtlwifi: btcoex: 23b 1ant: adjust wifi duration for bt a2dp 
The larger the bt a2dp bit pool is, the more time bt needs to receive
them. If we do not adjust the wifi duration, the voice quality will be
low. Hence we reduce the time that wifi holds, to improve the a2dp
service.

If the bt is slave, it may receive a packet at any time, so we
need to mark them as high priority packets in case of packet loss

12515a08e7 rtlwifi: btcoex: 23b 1ant: check PS state before setting tdma duration 
For time division multiple access, the wifi and bt take turns to
transmit, but we need to let AP know that wifi is under standby mode by
sending null data to "pretend" entering power saving state using lps
rpwm.

But, the fw does not know if it is the actual power saving mode or just a
fake one to cheat to the AP. Hence, before fw setting the tdma duration,
the fw needs the driver to check the power saving state first.
