Fix build on Kernel v. 6.12

[mfrischknecht]

asm/unaligned.h has been moved to linux/unaligned.h since Linux v. 6.12 ¹, which breaks the build of vendor-reset e.g. on NixOS unstable (and likely other distributions, as soon as those switch to 6.12, too).

On my system, the build fails with this error:

/build/source/src/amd/amdgpu/atom.c:32:10: fatal error: asm/unaligned.h: No such file or directory
   32 | #include <asm/unaligned.h>
      |          ^~~~~~~~~~~~~~~~~

unfortunately this breaks the build on previous kernels, should try to make this change conditional like this:

vendor-reset/src/amd/amdgpu/atom.c

Line 43 in 084881c

#if LINUX_VERSION_CODE < KERNEL_VERSION(4, 3, 0)

@VoodaGod I'm currently out of town, so I've just applied you suggestion through the GitHub mobile interface. I hope that's okay like this. Thanks!

Note: I havent tested this myself yet. I should be able to until friday.

For completeness' sake: I've also tested building the module with some older Kernels through my NixOS config and had no issues.

I didn't switch to these Kernels and test the functionality, but as there haven't been many logic related changes in the recent past (and I've used the module through multiple of these older Kernel versions myself), I don't anticipate any problems in that regard.

Kernel 6.12 made it into Debian Stable backports. Had to manually edit the DKMS source for now, can confirm this PR fixes the issue and works for both >=6.12 and <=6.11 kernels.
@gnif Can you merge this, please?

If anyone needs this fix on Arch using the AUR package, I was able to manually add it by updating the pkgbuild file. I started the reinstall using yay --editmenu -S vendor-reset-dkms-git, then entering the editor when prompted, and adding the prepare function to the build, which downloads and applies patches for the two commits in this PR.

prepare() { 
    cd "$srcdir/$_pkgbase" 
     
    wget "https://github.com/gnif/vendor-reset/commit/ab1b34848097587aca1f248958358ddb1dc90917.diff" 
    wget "https://github.com/gnif/vendor-reset/commit/54ffd6a012e7567b0288bc5fcc3678b545bd5aec.diff" 

    patch -p1 < "ab1b34848097587aca1f248958358ddb1dc90917.diff" 
    patch -p1 < "54ffd6a012e7567b0288bc5fcc3678b545bd5aec.diff" 
}

Will a fix be added for >=6.12 builds at some stage? This one is a red mark on the build server.
(Without having to edit the build script first)

I succefully install this version on Proxmox 9 and seem to work correctly

Edit
At the end I discovered that vendor-reset never work on my apu Ryzen 5626U.
My system was working using vfio and stop to work after the update to 6.14 Kernel versions so I must downgrade to 6.8. I don't know if and how to make this to work with my apu. I try to use AI to help but without success

Actually for me a resolve installing again the 6.8 kernel and set as default, practically as I understand vfio on 6.8 wasn't work for my integrated apu and this is way can be shutdown and wake more time without problems on windows or Linux VM without use vendor-reset, on new kernel instead vfio was able to do the reset but not correctly and so after one working launch the next one is working with glitches UI on the TV screen, when using RDP is okay and GPU is connected correctly, so it has some dirty status after reset and I can't find a way to say to vfio to do nothing after VM wake or shutdown to can try if work as the same as the 6.8 kernel version
