lp8788-buck: fix a parent deivce in _probe()
The lp8788-buck is a platform driver of lp8788-mfd. The platform device is allocated when mfd_add_devices() is called in lp8788-mfd. On the other hand, 'lp->dev' is the i2c client device. Therefore, this 'platform_device' is a proper parent device in case of resource managed mem alloc, registering a regulator and device kernel message.
