rtlwifi: btcoex: Remove 23b 1ant configuration parameter

Browse Source 
In file halbtc8723b1ant.c, there are directives that depend on an
undocumented configuration parameter BT_AUTO_REPORT_ONLY_8723B_1ANT
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.

The following routines are restored:
halbtc8723b1ant_bt_auto_report()
halbtc8723b1ant_set_bt_auto_report()
halbtc8723b1ant_action_wifi_only()
halbtc8723b1ant_monitor_bt_enable_disable()
