platform/x86: portwell-ec: Move watchdog device under correct platform hierarchy
Without explicitly setting a parent for the watchdog device, the device is
registered with a NULL parent. This causes device_add() (called internally
by devm_watchdog_register_device()) to register the device under
/sys/devices/virtual, since no parent is provided. The result is:
DEVPATH=/devices/virtual/watchdog/watchdog0
To fix this, assign &pdev->dev as the parent of the watchdog device before
calling devm_watchdog_register_device(). This ensures the device is
associated with the Portwell EC platform device and placed correctly in
sysfs as:
DEVPATH=/devices/platform/portwell-ec/watchdog/watchdog0
This aligns the device hierarchy with expectations and avoids misplacement
under the virtual class.
