[PATCH 10/40] [SRU][Lunar/OEM-6.1] wifi: rtw89: phy: ignore warning of bb gain cfg_type 4

[Koba Ko]

From: Ping-Ke Shih <pkshih at realtek.com>

BugLink: https://bugs.launchpad.net/bugs/2002601

The new BB parameters add new cfg_tpe 4 to improve performance of eFEM
modules (rfe_type >= 50), but we are using iFEM modules for now, so this
warning can be ignored.
