Subject: drm/amdgpu: add the IP discovery IP versions for HW INFO data
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
Git-commit: af14e7c2fc9b60af70b410a7dace116eaa5e4e65
Patch-mainline: v6.0-rc1
References: jsc#PED-1166 jsc#PED-1168 jsc#PED-1170 jsc#PED-1218 jsc#PED-1220 jsc#PED-1222 jsc#PED-1223 jsc#PED-1225 jsc#PED-2849

Use the former pad element to store the IP versions from the
IP discovery table.  This allows userspace to get the IP
version from the kernel to better align with hardware IP
versions.
