Summary
Add optional mt76x8_bt_en_gpio handling to the MT7668 Bluetooth SDIO reset path.
When a board exposes both mt76x8_pmu_en_gpio and a separate Bluetooth-enable GPIO, toggle the BT-enable GPIO low/high with the PMU reset so both sides of the SDIO combo module restart from the same power edge.
Why
Some MT7668 combo designs can leave the Bluetooth side in the previous state across a warm reboot while the Wi-Fi/PMU side is reset. Coordinating the optional BT-enable line with the existing PMU reset avoids that split reset state. If the property is not present, behavior is unchanged.
