Subject: [PATCH 1/4] wifi: rtw89: coex: Enable Wi-Fi RX gain control for free run solution

From: Ching-Te Ku <[email protected]>

When Wi-Fi & Bluetooth are both busy at the same time, Wi-Fi need to
enable RX gain to protect Wi-Fi RX RF ability. Without this configure
the interference from Bluetooth will bring a big impact to Wi-Fi RX.
