drm/amdgpu: Add map of logical to physical inst

Browse Source 
Add a map for logical to physical instances of an IP. For ex: on some device
configurations, the first logical XCC may not be the first physical XCC.
Software may continue to access in logical IP instance order. The map
provides a convenient way to get to the actual physical instance.
