[PATCH rtw-next v2 02/14] wifi: rtw89: 8922d: disable VCORE for thermal protection by default

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

From: Chih-Wen Hsiao <owen.hsiao@realtek.com>

To ensure the stability of the thermal protection mechanism,
the primary approach is to reduce the transmit (TX) duty cycle;
the option to lower the voltage(VCORE) is disabled by default.
