/sys/class/watchdog/watchdogn/device/modalias can help to identify the
driver/module for a given watchdog node. However, many wdt devices does not set
its parent and so, we do not see an entry for device in sysfs for such devices.

This patch fixes parent of watchdog_device so that
/sys/class/watchdog/watchdogn/device is populated.

Exceptions: booke, diag288, mpc8xxx, octeon, softdog and w83627hf -- They do not
have any parent. Not sure, how we can we identify driver for these devices.
