Peng Ju Zhou c89d2a2fe0 drm/amd/amdgpu: add instance_number check in amdgpu_discovery_get_ip_version
The original code returns IP version of instantce_0 for every IP. This implementation may be correct for most of IPs.

However, for certain IP block (VCN for example), it may have 2 instances and
both of them have the same hw_id, BUT they have different revision number (0 and 1).

In this case, the original amdgpu_discovery_get_ip_version cannot correct reflects
the result and returns false information
