watchdog: intel-mid_wdt: add MODULE_ALIAS() to allow auto-load

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.
