Also, i've tested this patch with the 5K patch, the UCLK then just never
gets initialized, so this patch is literally incompatible with 5K.

And also if ur wondering, what patch am i talking about you can see it here:
https://github.com/t2linux/linux-t2-patches/blob/main/7003-amdgpu-add-support-for-5K.patch

I still need to make combine patch (otherwise bad tearing in gnome/mutter), and i need to
enable 5K in EFI aswell to remove the shitty quirk to initialize display eariler than smu,
And make it usable with simpledrm.
