[ Impact ]

To support Sony IMX471 camera sensor for Intel IPU7 platforms.

$ cat /sys/bus/i2c/devices/i2c-SONY471A\:00/modalias

[ Test Plan ]

1. Install -proposed kernel oem-6.11/noble or linux-oem-6.14/noble
```
$ sudo apt-get install --no-install-recommends --yes \
    linux-oem-22.04b \
    linux-modules-ipu6-oem-22.04b \
    linux-modules-ipu7-oem-22.04b \
    linux-modules-usbio-oem-22.04b \
    linux-modules-vision-oem-22.04b
$ sudo apt-get install --no-install-recommends --yes \
    linux-oem-22.04c \
    linux-modules-ipu6-oem-22.04c \
    linux-modules-ipu7-oem-22.04c \
    linux-modules-usbio-oem-22.04c \
    linux-modules-vision-oem-22.04c
```

2. To verify dkms changes, install -proposed intel-ipu6-dkms.
```
$ sudo apt-get install --no-install-recommends --yes intel-ipu6-dkms
```

3. Check if the driver has correctly bound:
```
$ sudo dmesg|grep ipu

4. Try access via gstreamer plugin via the video device hidden from
general users:
```
$ sudo gst-launch-1.0 icamerasrc ! \
    video/x-raw,format=NV12,width=1280,height=720 ! \
    videoconvert ! \
    autovideosink
```

5. Try access webcam from https://webcamtests.com

[ Where problems could occur ]

The changes only take effect for kernels >= v6.10. And while this is a
new driver that is not yet upstreamed, it's has no effect to existing
systems.

[ Other Info ]

Targets Questing and Plucky because oem-6.11/noble, oem-6.14/noble will
migrate to hwe-6.14 based on linux/plucky, and hwe-6.xx based on
linux/questing.
