This mapping is required for split-frame workloads, which otherwise fail with 00000000-F8C53528: [GUC] 0441-INVALID_ENGINE_SUBMIT_MASK ... if the application is using the logical id to reorder the engines and then using it for the batch buffer submission. It's not a big problem on media version 11 and 12 as they have only 2 instances of VCS and the logical to physical mapping is monotonically increasing - if the application is not using the logical id. Changing it for the previous platforms allows the media driver implementation for the next ones (12.50 and above) to be the same, checking the logical id. It should also not introduce any bug for the old versions of userspace not checking the id. The mapping added here is the complete map needed by XEHPSDV. Previous platforms with only 2 instances will just use a partial map and should still work.
