iwlwifi: add bt full concurrency support
Adding the bluetooth full concurrency support for WiFi/BT combo devices.
Driver should configure uCode to operate in "full concurrency" mode (via
LUT) if both conditions are met:
- Antenna Coupling is more than 35dB
- WiFi Channel Inhibition Request is hornored by BT Core
Currently, there is no antenna coupling information provided by uCode;
use module parameter to specified the antenna coupling in dB.
When in "full concurrency" mode, driver need to download different LUT
to uCode while sending bt configuration command; also, driver need to
configure the device operate in 1x1 while in full concurrency mode.
