Latest patches failing on X1 Carbon Gen 11 using latest Ubuntu 24.04 oem kernel package

## Summary

Following the discussion in https://github.com/intel/ipu6-drivers/issues/187#issuecomment-2484864556, this documents my attempt to build and use the patched kernel. This is at the request of @sgruszka.

### Steps to build the kernel
1. Begin with a standard Ubuntu 24.04 build environment
2. Add "deb-src" to the types line in the `/etc/apt/sources.list.d/ubuntu.sources` file. Execute `sudo apt update`.
3. Install source and build packages as follows:
```
sudo apt update
sudo apt build-dep -y linux linux-image-unsigned-6.11.0-1007-oem
sudo apt install -y fakeroot llvm libncurses-dev dwarves
```
I'm using an unsigned schema because I can't build the signed Ubuntu package, obviously...
4. Get the source package: `apt source linux-image-unsigned-6.11.0-1007-oem`
5. `cd` to the kernel source directory and apply the following 4 patches using `patch -p1 < file`.
[patch1.txt](https://github.com/user-attachments/files/17821262/patch1.txt)
[patch2.txt](https://github.com/user-attachments/files/17821263/patch2.txt)
[patch3.txt](https://github.com/user-attachments/files/17821264/patch3.txt)
[patch4.txt](https://github.com/user-attachments/files/17821265/patch4.txt)
6. Use the debian scripts to prepare the source:
```
chmod a+x debian/rules
chmod a+x debian/scripts/*
chmod a+x debian/scripts/misc/*
fakeroot debian/rules clean
```
7. Edited the source name in the `debian.oem/changelog` file to build `*.deb` packages with a distinguishing version number. I arbitrarily picked `1000` for this.
8. Build the kernel with the debian scripts. This takes a while, of course:
``
fakeroot debian/rules clean
fakeroot debian/rules binary
``
9. This gives a bunch of `*.deb` files in the `..` directory. I installed these with the command: ```sudo dpkg -i linux-oem-6.11-headers-6.11.0-1007_6.11.0-1007.1000_all.deb linux-headers-6.11.0-1007-oem_6.11.0-1007.1000_amd64.deb linux-modules-6.11.0-1007-oem_6.11.0-1007.1000_amd64.deb linux-modules-ipu6-6.11.0-1007-oem_6.11.0-1007.1000_amd64.deb linux-image-unsigned-6.11.0-1007-oem_6.11.0-1007.1000_amd64.deb```
10. Finally: reboot
11. I need to turn off secure boot in order to launch the unsigned kernel

### Notes/problems/issue with this build
- If I use the Ubuntu noble-proposed kernel packages for `6.11.0-1007-oem`. The kernel modules fail to correctly configure the ov2740 and v4l2_loopback some large fraction of the time, perhaps 50-60% of the time. This can often be recovered by a few `modprobe -r ov2740` + `modprobe ov2740` followed by a `sudo systemctl restart v4l2-relayd.service` to restart the gstreamer.
- While the camera can be used in this state, it is not 100% reliable. It often requires restarts and resets by removing and inserting modules.
- When using the newly compiled kernel with the patches, the `video4linux` virtual devices seem not to be configured and therefore the gstreamer process fails to start from the service file.
- As mentioned in #187, this may be a consequence of using an unsigned kernel package with signed firmware. I'm not sure if this is the root cause of this failure or not.
