soc/mediatek/mt8195: Enable and initialize eint eint event mask register is used to mask eint wakeup source. All wakeup sources are masked by default. Since most MediaTek SoCs do not have this design, we can't modify the kernel eint upstream driver to solve the issue 'Can't wake using power button (cros_ec) or touchpad'. So we add a driver here to unmask all wakeup sources.
