rtlwifi: btcoex: Remove 92e 2ant configuration parameter
In file halbtc8192e2ant.c, there are directives that depend on an
undocumented configuration parameter BT_AUTO_REPORT_ONLY_8192E_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.
Upon the advice of Realtek, the auto report option is turned on with
this patch.
Routine btc8192e2ant_is_wifi_status_changed() is restored.
