media: ipu-bridge: Request non-continuous clock for ov5693 on IPU6
The ov5693 (INT33BE / OVTI5693) needs its MIPI clock lane gated while
idle for the IPU6 CSI-2 receiver to lock onto the link, which the sensor
driver does when the endpoint requests a non-continuous clock.
The same sensor works with a free-running clock on the IPU3, so request
it only for the IPU6 variants where it has been confirmed on hardware:
Tiger Lake, Alder Lake-P and Alder Lake-N.
