drm/amdgpu: Add unique_id and serial_number for Arcturus v3

Browse Source 
Add support for unique_id and serial_number, as these are now
the same value, and will be for future ASICs as well.

v2: Explicitly create unique_id only for VG10/20/ARC
v3: Change set_unique_id to get_unique_id for clarity
