The bus_info in v4l2_capability of IPU6 isys v4l2_dev is missing.
The driver didn't set the dev_parent of v4l2_dev, its parent is set
to its parent auxdev which is neither platform nor PCI device, thus
media_set_bus_info() will not set the bus_info of v4l2_capability, then
`v4l2-ctl --all` cannot show the bus_info.

This patch fixes it by setting the dev_parent of video_device and v4l2
framework can detect the device type and set the bus_info instead.

Fixes: 3c1dfb5a69cf ("media: intel/ipu6: input system video nodes and buffer queues")
