Well technically that'd be breaking ABI (very unlikely, but still). So
I'd rather have this SKL-specific patch (because we haven't committed to
SKL just yet) separate from the patch removing the formats for previous
platforms in case we need to revert. I'll cook the patch for previous
platform as a follow up.
