  To: dev

Currently compress, decompress and dma are allowed only when all 3
capabilities are on.
A case where the user wants decompress offload, if decompress capability
is on but one of compress, dma is off, is not allowed.
Split compress/decompress/dma support check to allow partial
transformations.
