drm/amdgpu: Fix channel_index table layout for Aldebaran 

Fix the channel_index table layout to fetch the correct
channel_index when calculating physical address from
normalized address during page retirement.
Also, fix the number of UMC instances and number of channels
within each UMC instance for Aldebaran.
