lp8788-ldo: fix a parent device in _probe()
The lp8788-ldo 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 regulators and device kernel messages.
