drm/amdgpu: Handle VRAM dependencies on GFXIP9.4.3

Browse Source 
[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.
