drm/amdgpu: support get xgmi information for Aldebaran

Aldebaran uses registers defined in header gc_9_4_2 but much of the xgmi
related functionality can be obtained by reusing the exisitng definition
from gfxhub_v1_1_get_xgmi_info. While adding support for Aldebaran, also
refactored code to better handle the new scenario.

drm/amdgpu/gmc9: Adjust GART and AGP location with xgmi offset (v2)

On hives with xgmi enabled, the fb_location aperture is a size
which defines the total framebuffer size of all nodes in the
hive. Each GPU in the hive has the same view via the fb_location
aperture. GPU0 starts at offset (0 * segment size),
GPU1 starts at offset (1 * segment size), etc.

For access to local vram on each GPU, we need to take this offset into
account. This including on setting up GPUVM page table and GART table
