When built with CONFIG_INTEL_MID_WATCHDOG=m, currently the driver needs to be loaded manually, for the lack of module alias. This causes unintended resets in cases where watchdog timer is set-up by bootloader and the driver is not explicitly loaded. Add MODULE_ALIAS() to load the driver automatically at boot and avoid this issue.
