Disable amdgpu SI/CIK support and backport upstream patch to prevent crashes (#4013)

Browse Source 
As we enabled SI/CIK support to fix crashes on bunch of AMD SoCs in #3957, the
amdgpu driver still crashes on some hardware. It seems to be some GX-217GA SoCs
or even GX-425GA in Fujitsu thin clients (even though the same SoC is fine on
T620).

To get to the state before update to kernel 6.12, disable amdgpu for these
platforms again (as it couldn't work properly there before OS 15.0) and just
backport the patch that fixes the crashes during probing when the driver isn't
compiled with SI/CIK support.

Fixes #4012

Subject: [PATCH] drm/amd: Handle being compiled without SI or CIK support
better
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
If compiled without SI or CIK support but amdgpu tries to load it
will run into failures with uninitialized callbacks.
Show a nicer message in this case and fail probe instead.
