Support AMD Image Signal Processing (ISP) unit V4.0

[You-Sheng Yang]

[SRU Justification]

[Impact]

Miss AMD MIPI camera 4.0 support.

[Fix]

* kernel: https://github.com/amd/Linux_ISP_Kernel/tree/4.0 based on v6.14-rc2.
* libcamera: https://github.com/amd/Linux_ISP_libcamera/tree/3.0 based on upstream v0.4.0.
  - this depends on bug 2092060

[Test Case]

1. install kernel from -proposed channel with camera module installed,

2. upgrade libcamera, pipewire, install libcamera-tools from prebuilt PPA https://launchpad.net/~vicamo/+archive/ubuntu/ppa-testfield

3. Test camera availability:
```
$ sudo cam -l
[0:00:16.776607397] [3034] INFO Camera camera_manager.cpp:327 libcamera v0.4.0
[0:00:16.778052318] [3039] WARN AmdIsp4 isp4.cpp:706 Env var LIBCAMERA_AMD_CONFIG_FILE not found
[0:00:16.778059201] [3039] WARN AmdIsp4 isp4.cpp:708 Using default config file 'config-default.yaml'
[0:00:16.778347069] [3039] INFO AmdIsp4 isp4.cpp:396 sensor id: 'ov05c_mipi0'
[0:00:16.778487742] [3039] WARN AmdIsp4 isp4.cpp:706 Env var LIBCAMERA_AMD_CONFIG_FILE not found
[0:00:16.778492591] [3039] WARN AmdIsp4 isp4.cpp:708 Using default config file 'config-default.yaml'
Available cameras:
1: (ov05c_mipi0)
```

4. Start camera streaming to check if it actually works:
```
$ gst-launch-1.0 libcamerasrc ! \
    video/x-raw,format=YUY2,width=1280,height=720,framerate=30/1 ! \
    videoconvert ! \
    autovideosink
```

[Where problems could occur]

This kernel driver revision is isolated from other components, and therefore should not project additional risk to amdgpu itself. It's still under development but sufficient for early platform enablement, and it is being upstreamed and is expecting to complete at v6.16.

[Other Info]

Nominate only for oem platform enablement. For Plucky or later, the current plan is to take the upstreamed revision instead if AMD can catch the mainline inclusion train. Otherwise, we may still have to fallback to this beta revision.

[You-Sheng Yang (vicamo)]

For kernels >= v6.13-rc2, it takes also fixes from bug 2112462 to be able to boot from AMD Strix Halo CRB, the only platform I have that equips AMD ISP camera module.

Verified linux-oem-6.14 version 6.14.0-1004.4 along with above fixes, as well as libcamera, pipewire from https://launchpad.net/~vicamo/+archive/ubuntu/ppa-testfield, on AMD Strix Halo CRB.
