[PATCH rtw-next 01/15] wifi: rtw89: 8922d: remove CCK bandwidth compensation

[Ping-Ke Shih <pkshih@realtek.com>]

From: Eric Huang <echuang@realtek.com>

Remove the 40MHz bandwidth compensation from CCK efuse gain calculation.
The design no longer requires the +3dB compensation for 40MHz channels.
