eint event mask register is used to mask eint wakeup source on mt8192.
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.
