phy: phy-mtk-tphy: keep default value of mcu_bus_ck_gate_en
The default value of mcu_bus_ck_gate_en is 1, if clear it, will prevent system to enter deep idle mode, so keep its default value and without affecting PCIe function. Signed-off-by: Chunfeng Yun <chunfeng.yun@mediatek.com> Signed-off-by: Kishon Vijay Abraham I <kishon@ti.com>
