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.
Fixes: 87a1ef8058d9 ("watchdog: add Intel MID watchdog driver support")
