rtlwifi: btcoex: Remove 23b 2ant configuration parameter

In file halbtc8723b2ant.c, there are directives that depend on an
undocumented configuration parameter BT_AUTO_REPORT_ONLY_8723B_2ANT
that cannot be set from Kconfig. This parameter is replaced by a
boolean in the main structure used by all routines. It still cannot
be changed dynamically, but it is easier to document.

Routines halbtc8723b2ant_set_bt_auto_report(), and
btc8723b2ant_bt_auto_report() are restored.
