leds-lp8788: fix a parent device in _probe() 

The lp8788-keyled 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 led device and device
kernel messages.
