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.

I don't see why you don't use the platform device as parent for mpc8xxx.

Note however that I did several updates to the mpc8xxx driver which
probably conflict with setting the parent. I'll take care of that.

Best regards
Uwe
