v4l2-dev: use parent field if the v4l2_device has no parent set.

From: Hans Verkuil <hverkuil@xs4all.nl>

Normally the parent device of v4l2_device is used as the video device
node's parent. But if it was not set, then use the parent field in the
video_device struct.

This is needed in the cx88 driver, which has one core v4l2_device but
creates multiple pci devices (one each for raw and mpeg video).

So you cannot associate the core v4l2_device with a particular PCI device,
but you can do that for each video_device.

Priority: normal
