[PATCH 074/159] drm/amdgpu: use physical_node_id to calculate aper_base

[Alex Deucher]

From: Hawking Zhang <Hawking.Zhang at amd.com>

Similar as xgmi connected gpu nodes, physical_node_id
* segment_size should be used to calculate the offset
of aper_base.

The asic type check is redundant. once physical_node_id
and segment_size are initialized, it should be count
on.
