[Impact]

Camera sensor ov05c10 is not probed automatically:
```
$ cat /sys/bus/acpi/devices/OVTI05C1:00/status
15
$ sudo dmesg | grep ipu
...
intel-ipu7 intel-ipu7: no subdev found in graph
intel_ipu7_psys.psys intel_ipu7.psys.40: psys probe minor: 0
```

[Fix]

* https://github.com/intel/ipu6-drivers/blob/master/patch/v6.8/0012-media-Support-ov05c10-camera-sensor.patch

[Test Case]

The new camera sensor should be probed automatically and function well:
```
$ sudo dmesg | grep ipu
...
intel-ipu7 intel-ipu7: Found supported sensor OVTI05C1:00
intel-ipu7 intel-ipu7: Connected 1 cameras
...
intel_ipu7_isys.isys intel_ipu7.isys.40: bind ov05c10 13-0010 nlanes is 2 port is 0
intel_ipu7_isys.isys intel_ipu7.isys.40: All sensor registration completed.
```

[Where problems could occur]

Some of the IPU6/IPU7 camera sensor drivers are not yet upstreamed, and ov05c10
is one of them. Expect further turning/bug fixes.

[Other Info]

While ov05c10 is currently only used on Intel Lunar Lake platform with oem-6.11
kernel, we will target kernels >= 6.11 at least for now. Nominating for
Unstable-6.12, Oracular-6.11 and certainly OEM-6.11.
