drm/amdgpu: Handle VRAM dependencies on GFXIP9.4.3
[For 1P NPS1 mode driver bringup] Changes required to initialize the amdgpu driver with frontdoor firmware loading and discovery=2 with the native mode SBIOS that enables CPU GPU unified interleaved memory. sudo modprobe amdgpu discovery=2 Once PSP TMR region is reported via the ACPI interface, the dependency on the ip_discovery.bin will be removed. Choice of where to allocate driver table is given to each IP version. In general, both GTT and VRAM domains will be considered. If one of the tables has a strict restriction for VRAM domain, then only VRAM domain is considered.
