Thanks for the heads up. Currently KFD won't work on APUs when IOMMUv2
is disabled. But Ray is working on fallbacks that will allow KFD to work
on APUs even without IOMMUv2, similar to our dGPUs. Along with changes
in ROCm user mode, those fallbacks are necessary for making ROCm on APUs

function if CRAT is broken.
v5: refine acpi crat good but no iommu support case, and rename the
title.
v6: fix the issue of dGPU initialized firstly, just modify the report
value in the node_show().
