[PATCH V2 3/6] rtlwifi: btcoexist: Add routines for RTL8812AE with single antenna

[Larry Finger <Larry.Finger@lwfinger.net>]

From: Troy Tan <troy_tan@realsil.com.cn>

The RTL8812AE needs different BT coexistence routines than does the
RTL8821AE. This patch adds the necessary routines for devices with a
single antenna.
