From: Leo Liu leo.liu@amd.com
commit b43aaee69d4327d05e7624d9471c17d015b4d67d upstream.
With the enablement of VCN Dec and Enc from user space, User space queries kernel for the IP information, if HW has UVD/VCE, the info comes from these IP blocks, but this could end up mis-interpret for VCN when they are in the union, the other way same when HW with VCN block.
